WebIt's called Gauss-Jordan elimination, to find the inverse of the matrix. And the way you do it-- and it might seem a little bit like magic, it might seem a little bit like voodoo, but I think you'll see in future videos that it makes a lot of sense. What we do is we augment this matrix. What does augment mean? It means we just add something to it.

WebNow about your O ( n 3 / 3): note that it takes approximately 2 n 3 / 3 operations to invert a generic matrix. For a triangular matrix, it takes half the number of operations, hence the n 3 / 3 in your book. A final note: while saying that something takes k n 3 operations is fine, writing O ( n 3 / 3) is quite strange.
