FLIPLR Reverse the Columns of a Matrix

Section: Array Generation and Manipulations

USAGE

Reverses the columns of a matrix. The syntax for its use is
   y = fliplr(x)

where x is matrix. If x is an N-dimensional array then the second dimension is reversed.

Example

The following example shows fliplr applied to a 2D matrix.
--> x = int32(rand(4)*10)
x = 
  <int32>  - size: [4 4]
 
Columns 1 to 4
 4  4  2  5  
 9  4  8  4  
 7  2  0  2  
 0  7  0  2  
--> fliplr(x)
ans = 
  <int32>  - size: [4 4]
 
Columns 1 to 4
 5  2  4  4  
 4  8  4  9  
 2  0  2  7  
 2  0  7  0  

For a 3D array, note how the columns in each slice are flipped.

--> x = int32(rand(4,4,3)*10)
x = 
  <int32>  - size: [4 4 3]
