Solve system of linear equations *A**x* =
*B* for *x* using QR decomposition

returns the solution to the system of linear equations `x`

= fixed.qrMatrixSolve(`A`

, `B`

, `outputType`

)*A**x* = *B* as a variable with the output type specified by
`outputType`

.

returns the solution to the system of linear equations`x`

= fixed.qrMatrixSolve(`A`

, `B`

, `outputType`

, `regularizationParameter`

)

$$\left[\begin{array}{l}\lambda {I}_{n}\\ A\end{array}\right]x=\left[\begin{array}{l}{0}_{n,p}\\ B\end{array}\right]$$

where *A* is an
*m*-by-*n* matrix, *B*is an
*m*-by-*p* matrix, and λ is the regularization
parameter.
