MATLAB: From a vector to a 3D array

3darrayreshaperesizevector

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 120×1.
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) =

A simple reshape gives the exact order that you request:
>> mat = reshape(vector,[6,5,4])
mat(:,:,1) =
  0.353158571222071  0.73172238565867  0.188955015032545  0.08112576886578526  0.306349472016557

And checking:
"See that for (2,1,1) the result that I need is 0.821194040197959"
>> mat(2,1,1)
ans = 0.8211940401979591
