WebGenerally this is because you never want to compute numerically the inverse of a matrix, its unstable often. However, in your case, its in the definition of the equation, so you may need to do some shenanigans to that equation to get rid of the inverse, no idea. WebMatrix Inverse A square matrix S 2R n is invertible if there exists a matrix S 1 2R n such that S 1S = I and SS 1 = I: The matrix S 1 is called the inverse of S. I An invertible matrix is also called non-singular. A matrix is called non-invertible or singular if it is not invertible. I A matrix S 2R n cannot have two di erent inverses.
