okay i wouldn’t know how to do a CR decomposition off the top of my head but it doesn’t look too bad?

#29760

i have had to do a QR decomposition and if you ask me they should be made illegal

#29761

anyway have my advanced matrix analysis review for my test in less than an hour

CR you can literally just derive it.

#29763

I’m making fun of how easy this is

#29764

Like I didn’t know how to do CR until I saw the problem and did it

#29765

It’s just what two matrixes give you a matrix

#29766

tbf this could describe literally any matrix decomposition

Anyway the trick to the problem was to realize yu didn’t actually need the second column. So you get one matrix that is first col and second col and then you just Wolfe for r

#29768

Solve

#29769

Cuz the second column is just the first column * -2. It’s redundant. Unnecessary if I want to go from C * R = A

#29770

So then you are left with [-1 0; 2 0; 4 4] = [-1 0; 4 4] * R

Anyway I’m more disappointed than I was when benguined didn’t know what phasors were
