How can i form a 3d matrix from a 2d matrix

Hello I am struck in a problem for long time. I have got a 2D matrix of size 19x1339. I have another parameter pi=p*ch*win. Where p=1;ch=21;win=56. I wish to make a 3D matrix of dimension pi x 19 x 1339 without inserting zeros in the matrix. Can anyone please help me? It is really very urgent. I am doing the following: Here WCOH and WCS have the dimension 19 x 1339.
pi=p*ch*win;
xcoh(pi,:,:)=WCOH;%ADD coherence feature for each window here
xcs(pi,:,:)=WCS;

The question is not clear. Where do you want to insert 1176? Please post a small example, with e.g. "pi=2" and "WCS=magic(2)".
Please do not use "pi" as name of the variable, because this shadows the builtin function pi, which replies teh value of Pi.

Perhaps you mean:
xcs = repmat(reshape(WCS, 1, 19, 1339), 1176, 1, 1);
But this 3D array would consist of 1176 identical slices and this redundancy would be really inefficient.
