Invertibility Criteria

Description

This lecture presents an additional criterion for the invertibility of a matrix, showing that a matrix is invertible if there exists another matrix such that their product results in the identity matrix. By demonstrating this theorem, the instructor illustrates how finding such a matrix can reduce the work needed to prove invertibility by half.
