hi, I am trying run an example python code in matlab function block in simulink but i am getting this error. it would be very helpful if you can suggest some solution.
Python(Spyder) code:
def test(a,b):
a = int()
b = int()
result = a + b
return result
MATLAB FUNCTION code:
function result = python(a, b)
result = 0
coder.extrinsic('py.example.test')
result = py.example.test(a, b) # error at this line(MATLAB expression '<output of py.example.test>' is not numeric)
end

Hi Rifshu,
I understand that you’re trying to resolve the error while calling Python Functionality from MATLAB.
The variables ‘a’ and ‘b’ in the python code are initialized as ‘int’ variables. The output of ‘py.example.test’, when called from MATLAB, returns a ‘py.int’ type. You can resolve the error by using the ‘double’ function in the ‘MATLAB FUNCTION code’.
result = double(py.example.test(a,b));
Please refer to the following MATLAB Answers and Documentation links to gain more insight on running Python code in MATLAB and Simulink:
Hope this helps!
