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 =
