Syntax

A_fud = Matrices.flipUpDown(A);

Description

Function flipUpDown computes from matrix A a matrix A_fud with flipped rows, i.e., A_fud[i,:]=A[n-i+1,:], i=1,..., n.

Example

A = [1, 2,  3;
     3, 4,  5;
    -1, 2, -3];

A_fud = flipUpDown(A);

results in:

A_fud  = [-1, 2, -3;
           3, 4,  5;
           1, 2,  3]
