Solving 3 by 3 matrix
WebFeb 29, 2016 · A frequent misuse of inv arises when solving the system of linear equations Ax = b. One way to solve this is with x = inv(A)*b. A better way, from both an execution time and numerical accuracy standpoint, is to use the matrix division operator x = A\b. This produces the solution using Gaussian elimination, without forming the inverse. WebSep 17, 2024 · Key Idea 2.5. 1: Solving A X = B.
