Can anyone help me with making a 2D matrix into a 3D matrix?
I have a (105504 x 3) 2d matrix and I need to make a 3D matrix of dimensions (6 x 3 x 17584) I need to take (6 x 3) consecutive matrices by row for 17584 layers.
Can anyone help me with this? I really appreciate any help

a - your array (105504 x 3)
out = permute(reshape(a.', 3,6,[]),[2 1 3]);

Please try
B = permute(reshape(A, 6, [], 3),[2 1 3]);

Andrei's code gave me the correct dimensions I needed, but I appreciate your quick and expert response.
Thank you much
