I have a 1x12 array, where each element is a vector of doubles (the vectors have different lengths). How can I convert to a NX12 array, where N is the length of the vector with most elements.

You could do this yourself, but by far the simplest solution is to download Jos's excellent padcat:

If C is your 1x12 cell array, then just do this:

padcat(C{:})

The 1x12 cell array had a few empty vectors as elements. This caused the function to give a subscripted assignment dimension mismatch error in X = cat(dim, varargin{:})

Replaced those vectors with nan and it worked fine. Thanks.
