Hello.

I am trying to extract values from a matrix according to certain restrictions, with no success! In the file attached is the attempt. Any help would be greatly appreciated.

From a quick observation:

You can remove i from your program altogether, and use j to index r.

But the problem lies in the fact that only the first if statement is within the for loop.

I think you want all three if statements in that loop.

 

Success!
