convert a 2D matrix into 3D matrix

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

Thank you @andrei and @Walter!!! Walter, your code gave me a 3D matrix (17584x6x3). Andrei, your code worked perfectly (3D matrix (6x3x17584), Thank you for the help guys, you are awesome!!!

keep it up!!!

Answer 1

[Andrei Bobrov]

a - your array (105504 x 3)

out = permute(reshape(a.', 3,6,[]),[2 1 3]);

Andrei, your code worked perfectly (3D matrix (6x3x17584)). Thank you very much.

Answer 2

[Walter Roberson]

Please try

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

Walter, your code gave me a 3D matrix (17584x6x3).

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

Thank you much
