Re: Polynomials in arbitrary basis

[Juan Pablo Carbajal]

Hi,

Sounds interesting. Could you share the repository where you host your code?
Also, you can create a package, compress it and provide an url, this
way anybody can install it from within octave

pkg install http://your.url

needs Octave >= 4.4
