Hey guys.
I have a problem when trying to use a python script in a matlab file. I've followed the instructions in the DOC "Call User-Defined Python Module" and the tutorial works.
But I have a custom package that I need to use. But I don't even get the file to run when I add the package import. My Python file looks like this:
from package import * %Import custom package from installed Conda environment
def solve(var):
do stuff
%Calculation using the functions defined in cstmpkg
return var %Return value to matlab for further processing
Is there anything that I did wrong? I installed python with conda and changed pyversion to the corresponding conda environment where the package was installed. Or is Matlab unable to use custom Packages? That would answer the question, but it would be sad, because that would make the feature kinda useless.
Thanks for the Ideas/answers.

I found the solution myself.
you have to start matlab directly from conda while the correct environment ist activated. (type "matlab" in conda).
And add this to you matlab script:
pathofDocument = fileparts(which('custompythonscript.py'));
if count(py.sys.path,pathofDocument) == 0
insert(py.sys.path,int32(0),pathofDocument);
end
I hope that this will help someone out there.
