That did it! Knew it was something silly. Now I have to study the results! Thank you! Regards

comment Mathematica Implementation of Householder’s Method
I am very familiar with this site, unfortunately, all of the code has been removed and the stuff is not copyable. I would have to retype that code and hope no errors are made. Thanks anyway! Regards

comment Mathematica Implementation of Householder’s Method
The example here uses a single vector, but we want to use it for a matrix. I suspect that you somehow call it for each row vector and somehow combine those. I am also concerned that this snippet does not use the sign test to determine the signs. Note, this paper is just an example, this is just Householder transforms. The paper was used only because it had code. Here is a Wiki example: en.wikipedia.org/wiki/Householder_transformation

Maybe I am missing something, but how do you use it to get the same result as the $4x4$ in the paper?

comment Mathematica Implementation of Householder’s Method
I agree with your comment of bad code. That is why I have the aside in my post. However, I just want something quick to see HH transformations from step to step. Do you know of an alternate approach or code or something built-in to MMA?

Is it possible to use something like PolarPlot so no conversion to Cartesian is necessary?

comment How to constrain the range of a plot o f a function to satisfy an inequality?
Do you mean something like this? f[x_]:=x^2; Plot[f[x], {x, -5, 5}, RegionFunction -> Function[{x,y}, f[x] >= 10]]
