Chapter 24 // Exercise 5 - Principles & Practice Using C++

In this exercise I am using Visual Studio 2019 and a modified version of the std_lib_facilities header found here.

Chapter 24 // Exercise 5

Try the Gaussian elimination program with A == { {0 1} {1 0} } and B == { 5 6 } and watch it fail. Then, try elim_with_partial_pivot().

Ok, so after seeing this exercise I have a feeling that A is supposed to be an Identity matrix? I messed around with the program and it always worked after I left A as given above; no matter what B was. I think A is always supposed to be an identity matrix....that is if I understood what maths is fun was going on about.

EDIT - So as this post was scheduled I made this edit 10 mins after moving onto exercise 6 when I realised that my randomMatrix function was complete garbage lol. A does not need to be an identity matrix.
