How to use the qrfact function?
In Julia, I would like to use the function qrfact(), which I thought was part of the LinearAlgebra package. However, when I attempt to use the function, Julia claims the function qrfact() is NOT defined. Is there perhaps any way I can use this specific function in Julia? I do not want to use the regular qr() function. I have attached a screenshot of the error message:
qrfact was apparently deprecated to just qr before the release of version 1.0 back in 2018: https://github.com/JuliaLang/julia/pull/27212
You don't say why you don't want to use 'regular qr', but since it's presumably the same as qrfact, it seems that's your only option.
If you are running old Julia code from pre-1.0, then a good course of action is to install v0.7, run your code and update it according to all the deprecation messages you get. After that you can safely transition to v1.x
