Examples
Create Python Package Using File
Create a Python package using a function file that generates a magic square.
In MATLAB, locate the MATLAB function that you want to deploy as a Python package. For this example, use the file magicsquare.m
located in
.matlabroot
\extern\examples\compiler
appFile = which('magicsquare.m');
Build a Python package using the compiler.build.pythonPackage
command.
compiler.build.pythonPackage(appFile);
The build function creates the following files within a folder named
magicsquarepythonPackage
in your current working directory:
GettingStarted.html
includedSupportPackages.txt
example
mccExcludedFiles.log
readme.txt
requiredMCRProducts.txt
pyproject.toml
setup.py
unresolvedSymbols.txt
Customize Python Package
Create a Python package and customize it using name-value arguments.
For this example, use the files flames.m
and
flames.mat
located in
.matlabroot
\extern\examples\compiler
appFile = which('flames.m'); MATFile = which('flames.mat');
Build a Python package using the compiler.build.pythonPackage
command. Use name-value arguments to specify the package name, add a MAT-file, and
enable verbose output.
compiler.build.pythonPackage(appFile, ... 'PackageName','FlamesApp','AdditionalFiles',MATFile, ... 'Verbose','on');
Create Multiple Python Packages Using Options Object
Create multiple Python packages using a compiler.build.PythonPackageOptions
object.
For this example, use the file magicsquare.m
located in
.matlabroot
\extern\examples\compiler
appFile = which('magicsquare.m');
Create a PythonPackageOptions
object using
appFile
. Use name-value arguments to specify a common output
directory, disable automatic detection of data files, and enable verbose output.
opts = compiler.build.PythonPackageOptions(appFile, ... 'OutputDir','D:\Documents\MATLAB\work\PythonPackageBatch',... 'AutoDetectDataFiles','off','Verbose','on')
opts =
PythonPackageOptions with properties:
FunctionFiles: {'C:\Program Files\MATLAB\R2024b\extern\examples\compiler\magicsquare.m'}
PackageName: 'example.magicsquare'
SampleGenerationFiles: {}
AdditionalFiles: {}
AutoDetectDataFiles: off
ExternalEncryptionKey: [0×0 struct]
ObfuscateArchive: off
SecretsManifest: ''
SupportPackages: {'autodetect'}
Verbose: on
OutputDir: 'D:\Documents\MATLAB\work\PythonPackageBatch'
Build the Python package using the PythonPackageOptions
object.
compiler.build.pythonPackage(opts);
To compile using the function file hello.m
with the same options,
use dot notation to modify the FunctionFiles
argument of the
existing PythonPackageOptions
object before running the build function
again.
opts.FunctionFiles = which('hello.m');
compiler.build.pythonPackage(opts);
By modifying the FunctionFiles
argument and recompiling, you
can compile multiple components using the same options object.
Get Build Information from Python Package
Create a Python package and save information about the build type, generated files,
included support packages, and build options to a
compiler.build.Results
object.
Compile using the file magicsquare.m
.
results = compiler.build.pythonPackage('magicsquare.m');
results = Results with properties: BuildType: 'pythonPackage' Files: {3×1 cell} IncludedSupportPackages: {} Options: [1×1 compiler.build.PythonPackageOptions]
The Files
property contains the paths to the following:
example
foldersetup.py
GettingStarted.html
Input Arguments
FunctionFiles
— Files implementing MATLAB functions
character vector | string scalar | cell array of character vectors | string array
Files implementing MATLAB functions, specified as a character vector, a string scalar, a string
array, or a cell array of character vectors. File paths can be relative to the current
working directory or absolute. Files must have one of the following extensions: .m
, .p
, .mlx
, or .mexa64
.
Example: ["myfunc1.m","myfunc2.m"]
Data Types: char
| string
| cell
opts
— Python package build options
compiler.build.PythonPackageOptions
object
Python package build options, specified as a compiler.build.PythonPackageOptions
object.
Name-Value Arguments
Specify optional pairs of arguments as
Name1=Value1,...,NameN=ValueN
, where Name
is
the argument name and Value
is the corresponding value.
Name-value arguments must appear after other arguments, but the order of the
pairs does not matter.
Before R2021a, use commas to separate each name and value, and enclose
Name
in quotes.
Example: OutputDir='D:\work\myproject'
AdditionalFiles
— Additional files
character vector | string scalar | cell array of character vectors | string array
Additional files and folders to include in the Python package, specified as a character vector, a string scalar, a string array, or a cell array of character vectors. Paths can be relative to the current working directory or absolute.
Example: 'AdditionalFiles',["myvars.mat","data.txt"]
Data Types: char
| string
| cell
AutoDetectDataFiles
— Flag to automatically include data files
'on'
(default) | on/off logical value
Flag to automatically include data files, specified as 'on'
or 'off'
, or as numeric or logical 1
(true
) or 0
(false
). A value of 'on'
is equivalent to true
, and 'off'
is equivalent to false
. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState
.
If you set this property to
'on'
, then data files that you provide as inputs to certain functions (such asload
andfopen
) are automatically included in the package.If you set this property to
'off'
, then you must add data files to the package using theAdditionalFiles
option.
Example: 'AutoDetectDataFiles','off'
Data Types: logical
ExternalEncryptionKey
— Paths to encryption key and loader files
scalar struct
Since R2024b
Paths to the external AES encryption key and MEX key loader files, specified
as a scalar struct with exactly two row char vector or string scalar fields
named EncryptionKeyFile
and
RuntimeKeyLoaderFile
, respectively. Both struct fields
are required. File paths can be relative to the current working directory or
absolute.
For example, specify the encryption key as encrypt.key
and
loader file as loader.mexw64
using struct
keyValueStruct
.
keyValueStruct.EncryptionKeyFile='encrypt.key'; keyValueStruct.RuntimeKeyLoaderFile='loader.mexw64'
The encryption key file must be in one of the following supported formats:
Binary 256-bit AES key, with a 32 byte file size
Hex encoded AES key, with a 64 byte file size
The MEX file loader retrieves the decryption key at runtime and must be an interface with the following arguments:
prhs[0]
— Input, char array specified as the static value'get'
prhs[1]
— Input, char array specified as the CTF component UUIDplhs[0]
— Output, 32 byte UINT8 numeric array or 64 byte hex encoded char array, depending on the key format
Avoid sharing the same key across multiple CTFs.
Example: 'ExternalEncryptionKey',keyValueStruct
Data Types: struct
PackageName
— Name of Python package
character vector | string scalar
Name of the Python package, specified as a character vector or a string scalar.
Specify 'PackageName'
as a namespace, which is a
period-separated list, such as
companyname.groupname.component
. The name of the
generated package is set to the last entry of the period-separated list. The
name must begin with a letter and contain only alphabetic characters and
periods.
If not specified, PackageName
defaults to the name of the
first MATLAB file listed in the FunctionFiles
argument.
Example: 'PackageName','mathworks.pythonpackage.mymagic'
Data Types: char
| string
SampleGenerationFiles
— MATLAB sample files
character vector | string scalar | cell array of character vectors | string array
MATLAB sample files used to generate sample Python files for functions included with the package, specified as a
character vector, a string scalar, a string array, or a cell array of character
vectors. Paths can be relative to the current working directory or
absolute. Files must have a .m
extension.
Example: 'SampleGenerationFiles',["sample1.m","sample2.m"]
Data Types: char
| string
| cell
SecretsManifest
— Path to JSON manifest file
character vector | string scalar
Since R2024b
Path to a secret manifest JSON file that specifies the secret keys to be embedded in the deployable archive, specified as a character vector or a string scalar. The path can be relative to the current working directory or absolute.
If your MATLAB code calls the getSecret
, getSecretMetadata
, or isSecret
function, you must specify the secret keys to embed in
the deployable archive in a JSON secret manifest file. If your code calls
getSecret
and you do not specify the
SecretsManifest
option, MATLAB
Compiler™ issues a warning and generates a template JSON file in the output
folder named
.
Modify this file by specifying the secret key names in the Embedded field.<component_name>
_secrets_manifest.json
The setSecret
function is not deployable. To embed secret keys in a
deployable archive, you must call setSecret
in MATLAB before you build the archive.
For more information on deployment using secrets, see Handle Sensitive Information in Deployed Applications.
Example: 'SecretsManifest','D:\Documents\MATLAB\work\mycomponent\mycomponent_secrets_manifest.json'
Data Types: char
| string
ObfuscateArchive
— Flag to obfuscate deployable archive
'off'
(default) | on/off logical value
Flag to obfuscate the deployable archive, specified as 'on'
or 'off'
, or as numeric or logical 1
(true
) or 0
(false
). A value of 'on'
is equivalent to
true
, and 'off'
is equivalent to
false
. Thus, you can use the value of this property as a
logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState
.
If you set this property to
'on'
, then folder structures and file names in the deployable archive are obfuscated from the end user, and user code and data contained in MATLAB files are placed into a user package within the archive. Additionally, all.m
files are converted to P-files before packaging. This option is equivalent to usingmcc
with-j
and-s
specified.If you set this property to
'off'
, then the deployable archive is not obfuscated. This is the default behavior.
Example: 'ObfuscateArchive','on'
Data Types: logical
OutputDir
— Path to output directory
character vector | string scalar
Path to the output directory where the build files are saved, specified as a character vector or a string scalar. The path can be relative to the current working directory or absolute.
The default name of the build folder is the package name appended with pythonPackage
.
Example: 'OutputDir','D:\Documents\MATLAB\work\mymagicpythonPackage'
Data Types: char
| string
SupportPackages
— Support packages
'autodetect'
(default) | 'none'
| string scalar | cell array of character vectors | string array
Support packages to include, specified as one of the following options:
'autodetect'
(default) — The dependency analysis process detects and includes the required support packages automatically.'none'
— No support packages are included. Using this option can cause runtime errors.A string scalar, character vector, or cell array of character vectors — Only the specified support packages are included. To list installed support packages or those used by a specific file, see
compiler.codetools.deployableSupportPackages
.
Example: 'SupportPackages',{'Deep Learning Toolbox Converter for
TensorFlow Models','Deep Learning Toolbox Model for Places365-GoogLeNet
Network'}
Data Types: char
| string
| cell
Verbose
— Flag to control build verbosity
'off'
(default) | on/off logical value
Flag to control build verbosity, specified as 'on'
or 'off'
, or as numeric or logical 1
(true
) or 0
(false
). A value of 'on'
is equivalent to true
, and 'off'
is equivalent to false
. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState
.
If you set this property to
'on'
, then the MATLAB command window displays progress information indicating compiler output during the build process.If you set this property to
'off'
, then the command window does not display progress information.
Example: 'Verbose','on'
Data Types: logical
