AM In the comp.lang.tcl newsgroup cuneyt announced the following:
At the following website you'll find a software called EasyNumerics.
http://www.me.metu.edu.tr/cuneyt/EasyNumerics
It is written in pure Tcl/Tk. I developed it to use in my numerical methods course as a teaching tool. It is designed to be used in a typical undergraduate level numerical methods course for engineers. It can solve problems about
Root Finding Solution of Linear Algebraic Equations Optimization Curve Fitting Numerical Differentiation & Integration Solution of ODEs
If you are also interested in doing math with Tcl/Tk, please feel free to download and use it. It is only tested by myself and my students, so I am sure there are many bugs in it, but still it can do quite a lot of things.
I will be very very happy to hear your feedback. If you have any suggestions or any feature that you think will improve the software, please let me know.
