cat2

Concatenate arrays of dissimilar/inconsistent sizes

Like the built-in function 'cat', this function concatenates arrays along a specified dimension. However, when the other dimensions of the input arrays do not match, nonexisting values are padded with a specified value.
C = CAT2(dim, padval, A, B)
C = CAT2(dim, padval, A1, A2, A3, A4, ...)

Examples:

C = cat2(3, 0, ones(3, 3, 1), 2*ones(4, 4, 2));
C = cat2(3, {[]}, cell(3, 3, 1), cell(4, 4, 2));

For convenience, horzcat2 and vertcat2 are also provided.
