How to convert matlab vector to 3D matrix

Question

I have a vector s, which is of size 1*163840 which comes from sizeX * sizeY * sizeZ = 64 * 40 * 60. I want to convert the 1*163840 vector to a 3-dimensional matrix, which has 64 in x-axis, 40 in y-axis, and 64 in z-axis.

What is the easiest way to convert it?

Answer 1

Use reshape to do it easily:

new_matrix = reshape(s, 64, 40, 60);
