Matlab, the most basic programming software, is very powerful, and there are many programming programs on the Internet that can download various algorithms in mathematical modeling. In basic use, it can replace lingo and SPSS and other mathematical statistics software. Of course, lingo and SPSS are more powerful and detailed in their respective functions.

It would be better if you can use a language, such as C/C++, which is not as convenient as matlab, but you can do more basic things.

Of course, typesetting can be used for editing papers, WORD and WPS software.
