MATLAB Function Reference

fliplr

Flip matrices left-right

Syntax

B = fliplr(A)

Description

B = fliplr(A) returns A with columns flipped in the left-right direction, that is, about a vertical axis.

If A is a row vector, then fliplr(A) returns a vector of the same length with the order of its elements reversed. If A is a column vector, then fliplr(A) simply returns A.

Examples

If A is the 3-by-2 matrix,

A =
    1    4
    2    5
    3    6

then fliplr(A) produces

    4    1
    5    2
    6    3

If A is a row vector,

A =
    1    3    5    7    9

then fliplr(A) produces

    9    7    5    3    1

Limitations

The array being operated on cannot have more than two dimensions. This limitation exists because the axis upon which to flip a multidimensional array would be undefined.
