Change from 3d array to 4d array

hello, I have a 3d array of size (M x N x L) & I want to change it to size (M x P x Q x L)

Where P&Q aren't product of N. For example (129*4*2) or anything instead of 4, to (129*349*1199*2)

it has to be changed to spatial dimensions 349*1199

Are you asking how to interpolate your data?

no sir, how can I change the 2nd dimension to become 2 different dimensions

Where P&Q aren't product of N.

One way might be to reshape it so that P*Q=N and then resize it, using imresizen() for example,
