FLIPDIM Reverse a Matrix Along a Given Dimension

Section: Array Generation and Manipulations

USAGE

Reverses an array along the given dimension. The syntax for its use is 
   y = flipdim(x,n)

where x is matrix, and n is the dimension to reverse.

Example

The following examples show some uses of flipdim on N-dimensional arrays. 
--> x = int32(rand(4,5,3)*10)

x = 

(:,:,1) = 
  5  4  5  3  9 
  7  7  5  6  7

--> flipdim(x,1)
