Webx = A\B solves the system of linear equations A*x = B. The matrices A and B must have the same number of rows. MATLAB ® displays a warning message if A is badly scaled or nearly singular, but performs the calculation regardless. If A is a square n -by- n matrix and B is a matrix with n rows, then x = A\B is a solution to the equation A*x = B ...

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. WebBeing able to augment and row-reduce is as good as being able to solve Ax=b, but maybe you prefer to have Sage give you the solution directly: M.solve_right(vector([7,13])) or b = vector([7,13]) M.solve_right(b) Let’s check it’s a solution: x = M.solve_right(b) M*x M*x==vector([7,13]) If you just use M.solve, though, you will get the wrong ...
