Assignment 5 make run command + NaNs with default case

For Assignment 5 where it says:

  • Add a 'run' target to your Makefile that runs the case P=400, N=200, T=10, and Δt=10e-5.

  • Submit your repo as a zip file and the output of the 'run' target by March 6, 2026.

Which one of the matrix multiplication modes should our 'make run' command use (since we have to submit an output file)?

Also when I run the above case, I find that most of the values are -nan by snapshot 4. is this because the given Δt=10e-5 is too large? (decreasing to 5e-6 doesn't result in this issue)

Yes, sorry that was a typo, it should have said 10^-6.

Thank you! And just to confirm, should our 'make run' command run all three matrix multiplications implementations?

They should all give very similar results. Submit the one for the third case.
