1.4 The Matrix Equation Ax b - University of California, Berkeley
WebSep 23, 2024 · Solves the equation a x = b by computing a vector x that minimizes the Euclidean 2-norm b - a x ^2. The equation may be under-, well-, or over- determined (i.e., … 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. inc gandhi
