1 August 2020
Here are some works of computer softwares Maxima, MATLAB and Mathematica,
and some notes on elementary topics.

MATLAB
is a commercial numerical analysis software widely used
in the world except for Japan.
This is a very important software for geometric tomography,
and HC is now studying how to use it.
Here are some examples of my outputs related with geometric tomography.

Mathematica
and
Maple
are commercial somputer algebra systems widely used
in the world including Japan.

Maxima
is a wellknown free computer algebra system.
Here are some maxima files and outputs used in my courses
on calculus, linear algebra and etc.
