The elements are taken column-wise from A to fill in the elements of the n1 -by For example, if A has size 2-by-6, then reshape A,4,[] returns a 4-by-3 array. Reshape V , which is a 1-by-4 row vector, into the 4-by-1 column vector Y. Here, V and Y must have the same number of elements.

Help Center Help Center. For example, reshape A,[2,3] reshapes A into a 2-by-3 matrix. You can specify a single dimension size of [] to have the dimension size automatically calculated, such that the number of elements in B matches the number of elements in A. For example, if A is a by matrix, then reshape A,2,2,[] reshapes the elements of A into a 2-byby array. Reshape a 4-by-4 square matrix into a matrix that has 2 columns. Specify [] for the first dimension to let reshape automatically calculate the appropriate number of rows. The result is an 8-by-2 matrix, which maintains the same number of elements as the original matrix. The elements in B also maintain their columnwise order from A.
