I can't. Mathematical modeling can't use pirated MATLAB. Pirated products may have a series of problems such as modeling errors due to imperfect program design, so they should use genuine products. Mathematical modeling is to establish a mathematical model according to actual problems, solve the mathematical model, and then solve the actual problems according to the results. When it is necessary to analyze and study a practical problem from a quantitative point of view, people should use mathematical symbols and language to establish a mathematical model on the basis of in-depth investigation, understanding of object information, making simplified assumptions and analyzing internal laws.
