# flip

Returns R, which is the matrix, m, flipped along the axis, a.

R = flip(m)

R = flip(m, a)

## Inputs

m
Type: string | mat
a (optional)
Specifies the axis about which the elements of m are flipped. If a is not specified, the first dimension of m greater than 1 is used as a reference for the flip operation.
Type: Positive, finite integer

## Outputs

R
Type: string | mat

## Example

Flip with the default axis:
R = flip([1,2,3,4;5,6,7,8;9,10,11,12])
R = [Matrix] 3 x 4
9  10  11  12
5   6   7   8
1   2   3   4
Flip with the axis specified:
R = flip([1,2,3,4;5,6,7,8;9,10,11,12], 2)

R = [Matrix] 3 x 4
4   3   2  1
8   7   6  5
12  11  10  9
