I want to use cellfun and make matlab go into each cell and reorder the column order, so that the new cell array has the same number of cells and the same matrix, except that the order of the columns should be (column 1, column 3, column 2, column 4).

one of the possible solutions
- if i understand you correctly...

c={
1:4
5:8
9:12
};
r=cat(1,c{:})
%{
% r =
1 2 3 4
5 6 7 8
9 10 11 12
%}
