1) Build a matrix called A consists of multidimensional arrays. This matrix contains three layers; each layer is 5x4 sub-matrixes. First sub-matrix is zeros matrix, second sub- matrix is ones matrix and last sub-matrix is positive random matrix. 2) Use reshape command to shape the matrix A to a new 15×4 matrix called B. 3) Create a new matrix called C by permuting array dimensions of A to three rows, five columns and four layers.
