Hi all

I have a 199x144 matrix but I want to switch the rows by starting from last row first. i.e.making last row as first row, row 198 as row 2, row 197 as row 3, and so on... Is there an easy way to do this?? (I could only think of looping by element but that will take so much time especially for bigger matrices).

Any help is appreciated! Thank you.
