Hi, can you clarify what is needed to be done with the following

multiply row 0 of the new matrix A_ref by -2 and add it to the row 1

After that operation will the row 0 remain the same or changed too?

add row 2 of the new matrix A_ref to the row 3, replacing row 3,

What changes and what remains the same?

2

Hmm, i suppose in the first one row 0 is multiplied first (so its changed) and then its added to row 1 (and row 1 is changed as well).

In the second instruction row 2 remains unchanged but row three changes.

3

Take a closer look at the previous exercise that had you fill in the code for multiple functions that perform row operations on matrices and see if you can use that to help you.

Hi all, Thank you for the responses. I figured out the confusion, and submitted my assignment hours ago.
