How to convert cell to matrix

I have a cell which is given by A= 1x13cell. I want to extract the contents of the cell into the form of a matrix of size (13 x number of points each cell containd) is this possible? The number of points in each cell varies. Can you help me with this?

I suggest you give a small example. For instance, if
C = {[1 2],[11 12 13]} % a cell array
how would you like the final matrix M to look like? Something like
1 2 NaN
11 12 13
?

This will only work for cells arrays containing matrices of constant size in each array.

Here is a suggestion
C = {[1 2 ;3 4],[11 12 13].',100:106} % a cell array
% make sure all elements are column vectors
C2 = cellfun(@(x) reshape(x,[],1), C,'un',0) ;
M = padcat(C2{:})
