Hi Ranjit,
Looks like you are calling MATLAB from C and using the functions like "engGetVariable" and "engPutVariable" to store and retrieve data of class object as described below:
Engine* ep = engOpen(NULL);
mxArray* tmp = engGetVariable(ep, 'clsObject.a');
But you are still not able to access the property "a" of the object "clsObject". Please try with other approaches as described below:
const char* command = "propValue = demoObj.a;";
engEvalString(ep, command);
// Fetch the variable holding the property value
mxArray* propValue = engGetVariable(ep, "propValue");
const char* command = "propValue = get(demoObj, 'a');";
engEvalString(ep, command);
// Fetch the variable holding the property value
mxArray* propValue = engGetVariable(ep, "propValue");
To learn more about calling MATLAB from c, please refer to the following documentation:
https://www.mathworks.com/help/matlab/calling-matlab-engine-from-c-programs-1.html?s_tid=CRUX_lftnav
In this documentation they have mentioned that this Engine API for C work with the MATLAB "mxArray" data structure, which is defined in the C Matrix API. To write applications using modern C++ features, see "Call MATLAB from C++".
Please refer to the documentation of "Call MATLAB from C++":
Hope it helps.
