Hello.
I have a 3D matrix: A( 5,5,10). For example if I have:
A(:,:,1) = [ 43 , 432 ,2, 34,3;
323 ,44,1, 9, 7 ]
Can I obtain an output like this:
A(:,:,1) = [ 1,2,3,7,9;
34,43,44,323,432]
If yes, how? Thanks!

You'd have to flatten the matrix into a 1d vector, sort that, then reshape it back to the initial shape. See https://in.mathworks.com/help/matlab/ref/reshape.html for how to reshape an array, and https://in.mathworks.com/help/matlab/ref/sort.html for how to sort. The code would be something like:
a = reshape(A, [250,1])
a = sort(a)
A = reshape(a, [5,5,10])

Thank you! It is almost how I wanted it.
For the moment the sorted values are column wise, so column1 row1 has minimum value and column1 row2 has the next minimum. I wanted something like: column1 row1 and then column2 row1.
But I think I might be able to work with this.
Thank you!
