Commonly used MATLAB, SPSS, SAS, and sometimes LINGO are also used. Few Great Gods use C language, because MATLAB is written in C language, which is more suitable for mathematical modeling and programming, and the program flow displayed in C language is not dominant.

Generally speaking, programming is not difficult, thanks to the powerful functions of MATLAB. There are certain requirements for the algorithm. As for the representation of data structure, I don't understand. Basically, it is to collect and process data, and modeling is the core link. This is done, the paper is not much different.
