c lang - different array length by pointer <p>I have problem with my own function for get array length.
Code:</p>

Python or Numpy Approach to MATLAB's "cellfun" <p>Is there a python or numpy approach similar to MATLABs "cellfun"? I want to apply a function to an object which is a MATLAB cell array with ~300k cells of different lengths. </p>
