Hi,
How can I add a specific column to an existent 3D matrix, as in this example?
A = 180 x 360 x 107 (MxNxt)
and I would like to add the first column from N (360) at the end of N to get 361 columns instead, thus to end with
B = 180 x 361 x 107 (MxNxt)
Thank you!

First, you need to realize that the size of your insert will be 180 x 1 x 107. I.e., it is not just a 180 element column you need to insert, but 107 of these columns ... one for each third dimension. I'm not sure what exactly you are trying to insert, but the general syntax would be
B = A;
B(:,361,:) = your 180 x 1 x 107 insert;
Or if you have a single column that you want repeated, you could employ repmat( ) on the right hand side.
What exactly are you trying to insert?
