Can anyone help me with making a 2D matrix into a 3D matrix?I have aI have a (616*780) 2d matrix and I need to make a 3D matrix of dimensions (616*780 x M) I need to take (616*780) consecutive matrices by row for layers,where M is the max value in the 2d matrix. Means I want to slice the 2D matrix.
I would appreciate it if anyone could help me! Thank you very much!

Here I used the multidimetional arrays
mat1(:,:,1)=[1,2,3,4; 5,6,7,8; 9,10,11,12];
mat1(:,:,2)=[1,2,3,4; 5,6,7,8; 9,10,11,12];
mat1(:,:,3)=[1,2,3,4; 5,6,7,8; 9,10,11,12];
disp(mat1);
Result:
(:,:,1) =
1 2 3 4
5 6 7 8
9 10 11 12
(:,:,2) =
1 2 3 4
5 6 7 8
9 10 11 12
(:,:,3) =
1 2 3 4
5 6 7 8
9 10 11 12
Check?

repmat(a,1,1,max(a(:))) % where a is your matrix if you have decimals in your matrix then use round function for max() to make the max value as an integer
