The easycnm library, written in Python, contains some useful methods for usage in numerical calculations. The purpose of the library is to learn and understand the algorithms, hence industrial-strength implementations should not be expected. It was written by Josef Spillner to waste some more space on the internet.
It is considered to be numerically unstable. In fact, the condition number has not been determined yet, and even a slight regression can not be ruled out at this point. It will not make you pass all exams magically. You have been warned.
The library is lincenced under GNU GPL conditions. Copying will not burn your cat, unless you try really hard.
