Hi there

Iβm using the LinearAlgebra package in Julia to use the QRPivoted method. The documentation is not very clear about the use of the tolerance. I want to use que qr pivoted function on a matrix A but I want to be able to change the tolerance.

To use the qr pivoted function, the documentation says to do the following:

```
qr(A, Val(false)) which actually works once you do it in Julia for any matrix A
```

However, the only mention of tolerance in the documentation is

qr(A::SparseMatrixCSC; tol=_default_tol(A), ordering=ORDERING_DEFAULT)

I donβt know how to use it in Julia because I have tried

qr(A, 10e-10, ordering = false) and

qr(A, 10e-10)

and nothing works. Can anyone help with that?

I would like to do something like

qr(A, Val(false), 10e-10) to make a QRPivoted matrix with a tolerance of the method of 10e-10.

It should work on any matrix A so feel free to use any one you want.

Thanks in advanced
