3-dimensional matrix dimension: row, column, page such as matrix A (m,n,w), M is row, N is column, W is page. When reshape a 3-D matrix, the elements of the matrix are taken in column order. First take the 1th page of the row, and then take the 2nd page, and so on. >> A=rand (2,2,2) A (:,:, 1) = 0.6787 0.7431 0.7577 0.3922 A (:,:, 2) = 0.6555 0.7060 3-dimensional matrix dimension: row, column, A page such as matrix A (m,n,w), M is a row, n is a column, and W is a page.
