I want to combine 4 matrices with dimensions:

z = 360x181x124

z1 = 360x181x124

z2 = 360x181x112

z3 = 360x181x124

I use the cat function:

z_T = cat(1,z,z1,z2,z3);

But i get the error "Dimensions of arrays being concatenated are not consistent."

I know why I get it but I dont know how I can solve it. Please help!

Those are 3-D images so you need to concatenate along the 4th dimension:

z_T = cat(4, z, z1, z2, z3);

unless you just want them in one big long 1-D vector, in which case you'd do this:

z_T = cat(1, z(:), z1(:), z2(:), z3(:));

OK, well close. Is it close enough for you to "Accept this answer"?

Yes ;)
