Calculating the inverse of a matrix

Thus to undo matrix multiplication, you need to multiply by the inverse matrix. It is thus a pretty fundamental operation. One early application for inverse matrices is to solve systems of linear equations. You can express the system as a matrix equation AX=B, then solve it by multiplying by the inverse of the coefficient matrix to get X = A^(-1)*B

Sep 17, 2022 · One way in which the inverse of a matrix is useful is to find the solution of a system of linear equations.
