In fact, the students in charge of programming don't mean that the code is longer than anyone who writes it well, but they want to provide a result to the students who model it (only winning the prize from the mathematical model (from the utilitarian point of view). No matter whether the result is good or bad, even if there is a result, the modeling teammates should be given an "answer" from the past at the end of the game, so some "fools" can be used when doing some mathematical model problems. This software can solve many statistical problems, such as the evaluation of 20 12 national wine, which is the representative of SPSS. Therefore, it is better to say that you should use relevant software, so that the model can output a good result. And the drawing software Origin. In some simple drawings, Origin can be used instead of Matlab. Generally speaking, it is not necessary to use Matlab when the problem is not too complicated. There is also a software called Visio, which is a sharp tool for drawing flowcharts. For example, when writing a program, attach a program block diagram, or draw a system flow chart when solving a problem with system dynamics, the effect is very good (PS: students who are learning modeling for the first time should work hard on Matlab anyway, even if they can't master it, they should know how to modify other people's excellent programs for us).
