I found a mathematica package that is particularly useful to me, published in (a highly cited work) a scientific journal. This package supposedly performs the
Tanh method for nonlinear partial differential equation and helps circumvent all the tedious algebra that follows if done by hand.
Alas, it would seem that the authors (quite mean of them) have not shared this package online and I cannot find it. I have checked general google searches with the package name and also checked packagedata.net.
I do have the original paper (shared here) in which the last couple of pages have the package.
Is there any way I can extract this package from the pdf or should I copy and paste into a text file (highly error prone since fonts are messy in this pdf) and then deal with it?
Am I missing something?
