Computes the least squares solution of the linear system of equations
Ax=b.
Num.LeastSquaresQR(Mat:MAT, Vec:MAT):MAT

Please note: The function(s) explained on this page is/are using the
ApCoCoAServer. You will have to start the ApCoCoAServer in order to use it/them.
This command computes the least squares solution of the linear system of equations
Ax=b, if there is no exact solution. The matrix
Mat must have the same number of rows as
Vec.
The QR decomposition of
Mat is used to find the solution.
- @param Mat Matrix A of the linear system of equations.
- @param Vec Vector B as a matrix.
- @return The least squares solution to Ax=b.
Dec(Num.LeastSquaresQR([[1,1],[0,1],[1,1]],[[0],[1],[0]]),2);
