concatenate vectors of an cell array in matlab

Question

In matlab I have a 4x5 cell array where each cell consists of an 121x1 vector.

What is the easiest way to create an 3-dim 4x5x121 matrix avoiding a 2-fold loop.

Answer 1

One way (not necessarily the fastest)

%# convert all arrays in the cell array inCell to 1x1x121
permCell = cellfun(@(x)permute(x,[3,2,1]),inCell,'uniformOutput',false);

%# catenate
array = cell2mat(permCell);
