MATLAB: Converting 2d matrix to 3d

matrixpermutationreshape

Can anyone help me with making a 2D matrix into a 3D matrix?

I have a (71680 x 8) 2d matrix and I need to make a 3D matrix of dimensions (512 x 8 x 140) I need to take (512 x 8) consecutive matrices by row for 140 layers.

Can anyone help me with this? I really appreciate any help

HI Joe,

if I'm not mistaken, it should be

permute(reshape(X, 512, 140, 8), [1 3 2]);

a - your array (105504 x 3)

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

It will work with reshape and permute. I guess you want this:

X = rand(1632, 11);
Y = permute(reshape(X, 32, 51, 11), [1, 3, 2]);

If you want something else, simply play with the order. For some results an initial permutation (e.g. a transpose) is required.
