This shows the relationship between the impulse response and the transfer function of an LTI (Linear Time-Invariant) system. It also illustrates how to obtain the output of the system to an input using the transfer function or state space representation through MATLAB/Simulink. ...
impulse这个函数没定义,也就是说缺少这个函数,这个应该是自定义的一个函数 xxppno1 我勒个去 8 function [yout,x,t] = impulse(a,b,c,d,iu,t)%IMPULSE Impulse response of dynamic systems.%% IMPULSE(SYS) plots the impulse response of the dynamic system SYS. For % systems with more than one...
