I need to call a Python function from MATLAB. how can I do this?
I had a similar requirement on my system and this was my solution:
In MATLAB there is a function called perl.m, which allows you to call perl scripts from MATLAB. Depending on which version you are using it will be located somewhere like
Create a copy called python.m, a quick search and replace of perl with python, double check the command path it sets up to point to your installation of python. You should now be able to run python scripts from MATLAB.
A simple squared function in python saved as "sqd.py", naturally if I was doing this properly I'd have a few checks in testing input arguments, valid numbers etc.
import sys def squared(x): y = x * x return y if __name__ == '__main__': x = float(sys.argv) sys.stdout.write(str(squared(x)))
Then in MATLAB
>> r=python('sqd.py','3.5') r = 12.25 >> r=python('sqd.py','5') r = 25.0 >>
