Lets say I have a matrix A=[1 2 3;2 4 5;6 5 4] and I want to find value at i=2 j=3 which is 5. But I want that program finds that value for me. For example i want something like that, short description " if at i=2 j=3 value is 5, end program, else check i=3 j=1". I would appreciate if someone can help me.
