# 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

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