I think the key for this are how you stone the matris?
Easy is stone data as xy grid.

struct matris {
int x;
int y;
int * list;
}
And use this for get and some like for save.
int get(matris submem,int x, int y) {
   return submem.list[x+submem.x*y];
}

You can read how the work.

you most fist get the new size of matris for make a new struck.
After this i well use loops for do the calc foreach cell in matris.
