How to find the inverse of a matrix (formula and examples)

WebFrom your description, it looks like you accidentally multiplied by 1/det (A) when it wasn't necessary. The determinant is only used to find the inverse itself. However, finding the inverse is (as you found out first hand), pretty difficult and prone to error. 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. how is irr used
