Hello
I created an array in order to put the results into it. Meanwhile, my matrix is 3D.
The 3D matrix is:
[4,3,2]=size(S)
And the created array is:
Result=[];
Is that a true definition?
Cheers

In general preallocation of matrices is not necessary in Matlab (it does increase speed, but is not necessary).
Just fill your matrix with the data and you should be fine. If you want to preallocate, use the solution that Siva showed. Zeros instead of rand might be an even better way.

k = rand(4,3,2) ; % create random 3d data
[m,n,p] = size(k) ; % get size
