shiftdim

Shift array dimensions

Syntax

• B = shiftdim(A, n)

• B = shiftdim(A)

• [B, m] = shiftdim(A)

Input argument

• A - Input array: vector, matrix or multidimensional array.

• n - Number of positions: integer value.

Output argument

• B - vector, matrix, or multidimensional array.

• m - Number of dimensions removed: non-negative integer.

Description

shiftdim(A, n) reorganizes the dimensions of an array A by n positions.

Specifically, when n is a positive integer, it shifts the dimensions to the left, and when n is a negative integer, it shifts the dimensions to the right.

Example

A = rand(2, 3, 4);
size(A)
% Shift the dimensions of array A by 2 positions to the left
B = shiftdim(A, 2)
