Ax=b, if matrix A is unknown? Physics Forums
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. WebIf (2,0) is a solution of the linear equation 2x+3y=k, then the value of 2k is.
