提高MAtlab编程技巧 书中主要以实例形式进行介绍，简便易学，是一本不可多得的好书(Improve you matlab skill: Many of the examples in the fi rst half of the book are not idiomatic MAT- LAB. I address this problem in the second half by translating the examples into a more standard style.)

说明：  function [ret,x0,str,ts,xts]=s4(t,x,u,flag) s4 is the M-file description of the SIMULINK system named s4. The block-diagram can be displayed by typing: s4. SYS=s4(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.

IMPEDANCE - computes input impedance, for one lumped port Syntax: impedance Description: IMPEDANCE computes the frequency behavior of the antenna input impedance. It also computes the feed power (which coincides with the total radiated power only for lossless antennas). The frequency range and the number of steps should be given below.
