I suggest you buy this book. After seeing this math experiment, you add the Matlab function instructions in this book. While reading, you can master the functions of matlab according to usage. I don't know where to check the function of the manual. This is more effective than a simple MATLAB tutorial. I wish I could see more clearly.

Suggestion: Mathematical Experiment (matlab Edition) Tongji University Press; "MATLAB7.0 from entry to mastery" People's Posts and Telecommunications Publishing House.
