00MATLAB This toolbox mainly consists of three parts (supporting platform MATLAB5.3 or 5.2, symbolic mathematics, optim, spline, Stats) 1. Chinese help of MATLAB 2 common mathematical modeling tools. Contribution to MATLAB mathematical modeling tools (marked with *) 3. Installation steps of MATLAB program in mathematical modeling competition for Chinese college students over the years 1. Unzip MATHMODL.zip to MATLAB11\ toolbox \; 2. Start Matlab, and use the Add path menu in the Path Browser to add MATLAB11\ toolbox \ mathmodl to the path, put it at the front and save the settings; 3. Go back to your work directory. Now MATHMODL has become an ordinary toolbox. You can use the help mathmodl command to view the content, or you can learn the tutorial directly with the mathmodl command.
