i need to transfer matrix coordinates in a specific order

hi i have a matrix and i need to take all the coordinates like this:

new_columns=old_rows+old_columns/2 and new_rows=old_rows-old_columns/2

i tried using meshgrid like this but i'm stuck i can't figure out how to apply this "meshgrid" operation from the old matrix to the new matrix

this is my code so far:

N=5;
s=-N:N;
s_0=-N:N;
[S_0,S]=meshgrid(s_0,s);
NEW_COL=S-S_0./2;
NEW_COL=fix(NEW_COL);
NEW_ROW=S+S_0./2;
NEW_ROW=fix(NEW_ROW);

It's not clear to me what form you wish the two new matrices to have. The following is just my guess. Perhaps if you give concrete example of what you want, we wouldn't have to guess.

 new_columns = (A.'+A)/2;
 new_rows    = (A-A.')/2;
