question

i want to create a matlab-like cell array in numpy. how can i accomplish this?

answer

matlab cell arrays are most similar to python lists, since they can hold any object - but scipy.io.loadmat imports them as numpy object arrays - which is an array with dtype=object.

to be honest though you are just as well off using python lists - if you are holding general objects you will loose almost all of the advantages of numpy arrays (which are designed to hold a sequence of values which each take the same amount of memory).
