I would like to create a 3D array from a vector. As an example, the size of the could be 6x5x4 and the vector is 120x1.
I tried to reshape function but the elements order of the array "result" are not correct
I copied the solution that I should obtain for the array result for a (:,:,1)
% result(:,:,1) =
Columns 1 through 4

"I tried to reshape function but the elements order of the array "result" are not correct"
Sure. But you did not tell us what the "correct" order should be.

A simple reshape gives the exact order that you request:
>> mat = reshape(vector,[6,5,4])
mat(:,:,1) =

@Stephen Cobeldick, thank you for your quick replay.
I copied the results that I have to obtain. The order that you propose is not the correct that I need.
See that for (2,1,1) the result that I need is 0.821194040197959 and in the code you proposed is 0.649115
