Either python is not installed in your system or it is not on your MS Windows PATH as known to MATLAB.

Inside MATLAB, command

getenv('PATH')

and see what it shows.

Note: python is not automatically installed as part of MATLAB. perl is, though, installed as part of MATLAB.

Found that you can get results back from python invoked from matlab by using [s,r] return values for system call where the strings python emits can be captured and parsed. Might be good to use files holding larger amounts of data with names printed for matlab to pick up and read.

A simple test I did was to write a squaring function and pass args:

>> arg1 = "1 2 3 4 5";
>> [s,r] = system(sprintf('python pysqr.py %s', arg1));
>> r
r =
    'argument 1: 1
     arg: 1 - sqr: 1
     argument 2: 2
     arg: 2 - sqr: 4
     argument 3: 3
     arg: 3 - sqr: 9
     argument 4: 4
     arg: 4 - sqr: 16
     argument 5: 5
     arg: 5 - sqr: 25
