Description : How to find the inverse of a square matrix?
Last Answer : You can factorize the matrix using LU or LDLT factorization algorithm. inverse of a diagonal matrix (D) is really simple. To find the inverse of L, which is a lower triangular matrix, you can find the answer in this link. ... )-1 = (A-1 )T for all matrix, you'll just have to find inverse of L and D.
