Hi, I'm having a matrix of size X= [280,307,191] and i want to restore the matrix such that the 3rd dimension of the matrix is multiplied by '12'
Thank you

You misunderstood the discussion in your prior question. Anyway, to do what you're asking for here (which is not what you really want):
A = 12 * A;
Why? Because, of course, every voxel has a Z value. I bet you're confused now, so better go back to your prior question and figure out what you really want to do.

If you want a matrix multiplication do
theProduct = w * Cm
% or
theProduct = Cm * w
