Dear All, I would like to compile my matlab function to python package library. Thus, I make a function parser , i.e. loadObject, printObject, etc. from my matlab object handle. However, is it possible to pass matlab object handle using matlab struct for python? I remember, I did that for my implementation in C using mwArray. Is there any similar library? I can't using matlab engine since it requires matlab license Thank you, Ryvo Octaviano function var = loadObject() var.obj = matlabClass(); end function printObject(var) printObject(var.obj); end classdef matlabClass < handle properties a = 1; end methods function obj = matlabClass() end function printObject(obj) disp(obj.a) end end end function TestScript() var = loadObject(); printObject(var); end I got this error: Traceback (most recent call last): File "loadObjectSample.py", line 15, in varOut = my_TESTJava.loadObject() File "C:\Program Files\MATLAB\MATLAB Runtime\v96\toolbox\compiler_sdk\pysdk_py\matlab_pysdk\runtime\deployablefunc.py", line 80, in __call__ nlhsWasSpecified, stdoutObj, stderrObj).result() File "C:\Program Files\MATLAB\MATLAB Runtime\v96\toolbox\compiler_sdk\pysdk_py\matlab_pysdk\runtime\futureresult.py", line 135, in result raise e File "C:\Program Files\MATLAB\MATLAB Runtime\v96\toolbox\compiler_sdk\pysdk_py\matlab_pysdk\runtime\futureresult.py", line 123, in result raise e File "C:\Program Files\MATLAB\MATLAB Runtime\v96\toolbox\compiler_sdk\pysdk_py\matlab_pysdk\runtime\futureresult.py", line 113, in result self._nlhs, out=self._out, err=self._err) matlab_pysdk.runtime.MatlabRuntimeError: An error occurred when evaluating the result from a function.

Dear All,

I would like to compile my matlab function to python package library. Thus, I make a function parser , i.e. loadObject, printObject, etc. from my matlab object handle.

However, is it possible to pass matlab object handle using matlab struct for python? I remember, I did that for my implementation in C using mwArray. Is there any similar library?

I can't using matlab engine since it requires matlab license

Thank you,

function var = loadObject()
    var.obj = matlabClass();
end
function printObject(var)
    printObject(var.obj);
end
classdef matlabClass < handle
    properties
        a = 1;
    end
        
    methods
        function obj = matlabClass()
        end
        function printObject(obj)
            disp(obj.a)
        end
    end
end
function TestScript()
    var = loadObject();
    printObject(var);
end

I got this error:
