A few days ago I was exploring the ideas behind implementing matrix inversion from scratch using … Web21. The formula for the determinant of an n by n matrix given by expansion of minors involves n! terms. As such, computing the determinant of a given matrix of with integer entries via expansion by minors takes a number of steps is bounded below by n! . (In practice the number of steps required depends on the size of the matrix entries).
