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)
