This feature provides a lightweight interface for accessing MATLAB® Runtime data. It allows data to be shared between a MATLAB Runtime instance, the MATLAB code running on that MATLAB Runtime, and the wrapper code that created the MATLAB Runtime instance. Through calls to MATLAB Runtime User Data interface API, you access MATLAB Runtime data through creation of a per-instance associative array of
mxArrays, consisting of a mapping from string keys to
mxArray values. Reasons for doing this include, but are not limited
You need to supply run-time information to a client running an application created with the Parallel Computing Toolbox™. Profile information may be supplied on a per-execution basis. For example, two instances of the same application may run simultaneously with different profiles.
You want to initialize MATLAB Runtime with constant values that can be accessed by all your MATLAB applications
You want to set up a global workspace — a global variable or variables that MATLAB and your client can access
You want to store the state of any variable or group of variables
Compiler SDK™ software supports per-run-time instance state access through an
object-oriented API. Access to a per-run-time instance state is optional, rather than on by
default. You can access this state by adding
getmcruserdata.m to your deployment project or by specifying them on
the command line. Alternatively, you use a helper function to call these methods as
demonstrated in Supply Run-Time Profile Information for Parallel Computing Toolbox Applications.
