Matlab Simulation in Signals & Systems Using Matlab at Different Levels

This paper describes the simulation by Matlab in the course of signals and systems. Matlab’s rich and powerful functions provide various methods to analyze the signals and systems, including both continuous and discrete situations. Some methods can simplify the complicated calculation; some finish the same functions in accordance with the mathematical processing; and some can save operation time via efficient algorithms. That is to say, Matlab can be used at different levels to help students solve problems quickly and efficiently, or help them understand the signal processing procedures deeply and in detail, even apply their knowledge on data structure to develop some new algorithms. Matlab helps to make the boring theoretical study less abstract and more vivid and has become an important auxiliary teaching method being used widely.
