TI-nspire CX Pivot and Simplex

[Christopher Zenzel]

> Hello everyone,
>
> My name is Christopher Zenzel and I am currently a student at Bucks County Community College. I am currently in a class that requires the use of the Simplex and Pivot methods with the TI-84. I use the TI-84 for the course primarily, but i just got an Ti-Nspire for some of my other work and classes.

> I haven't had much chance to try the pivot program, but the other programs work great (Simplex). I used a lot of source code, as a reference, from http://people.richland.edu/james/ti82/download.html. I converted it to the TI-nspire and the Simplex method has been working for me.

Thanks for posting this, Christopher. I made a library file for the
simplex method a few years ago bastardized from earlier TI calculator
programs. Here is the latest version:

Perhaps we can work together to make a "perfect" library file to share
with others.
