How to batch convert to C/C++ using Coder App?

Hi,

I have a large Matlab package that consists of hundreds of m files. They are in several folders, some start with '+'.

How do I batch convert them to C/C++ using Coder App? Do I have to run Coder App one-by-one?

Thanks.

Hi Shawn,

It is my understanding that you want to batch convert a large MATLAB package consisting of many M files into C/C++ code using the “MATLAB Coder App”.

Although the “MATLAB Coder App” does not support batch processing of multiple files directly in one go, however, you can automate the process using a script that calls the “codegen” function for each entry-point function.

Here’s how you can do it:

• Organize Your Code: Ensure that your MATLAB code is structured properly, with entry-point functions accessible for code generation.
• Create a Script for Batch Processing: You can write a MATLAB script to loop through your entry-point functions and generate the C/C++ code. Here’s an example:

% List of entry-point functions 
entryPoints = {'function1', 'function2', 'function3'}; % Add your function names here 

% Loop through each entry-point function 
for i = 1:length(entryPoints) 
    % Generate C/C++ code for each function 
    codegen(entryPoints{i}, '-args', {zeros(1, 10), zeros(1, 10)}); % Adjust input arguments as needed 
    End 

For any queries on “codegen” fuction, kindly refer to the MathWorks documentation linked below:

https://www.mathworks.com/help/coder/ref/codegen.html

• Run the Script: Execute the script in MATLAB, and it will generate the C/C++ code for each specified function.
• Using the Coder App: If you prefer using the MATLAB Coder App, you will need to manually select each function and specify input types, which can be time-consuming for many files.

By using the approach mentioned above, you can efficiently generate C/C++ code for multiple functions without having to run the “Coder App” for each function separately.

Hope this helps!
