I totally forgot about this. I've been doing that Aleks thing all day and you know how time filies when you're having too much fun.
Anyway, like everyone has said before, we learned about Matrices and Cramer's Rule. But I think anyone convered transpose, so I go over that.
Transpose is really simple, just switch the dimensions of the matrix. ex. 2x3 = 3x2
[2 3
5 6
9 1 ]
= [ 2 5 9
3 6 1]
There you go.
