...By simple you can understand easy to program (smib is a dynamically typed language, with strong affinity to recursivity, programs are often short and powerful and maybe useful for teaching), and also easy to modify (source code is free, written in C language, and based on notions of stacks and lists).
In this version :
- some bugs corrected
- new examples in smib-0.48/documentation/application/eigenmath/
those examples are here : eigenmath.org (with explanations), they are just adapted to smib.
smib roots are here : http://www.eigenmath.org/
