Line and file: Unknown line, matmul.s or test_matmul.s

Expected behavior: Outputs: 102 126 150

Observed behavior: Outputs: Venus ran into a simulator error!
Attempting to access uninitialized memory between the stack and heap. Attempting to access '4' bytes at address '1073741968'.

Question: I can't get my matmul to work correctly, I'm not sure what I'm doing wrong.

Also I read some of the other posts and testing in venus online was recommended, in that case would I just copy and paste and edit test_matmul, utils.s, and matmul.s so they could run as a single file on venus?

There are some algorithmic problems in your code. For example, in lines 57-59 of matmul.s,  you're not calculating the formula you've written in line 55 (there's a problem with this formula too and s2 should be replaced with s3).

Basically, this error means that you're might be trying to reach an out-of-bound element. Make sure that all of your pointer calculations are correct.

Thank you very much, I figured out exactly how I was messing up algorithmically. Everything works now.
