sys = tf(b,a)
其中a、b分别为微分方程左端和右端各项的系统向量。
例如系统方程
该方程左边、右边的系数向量分别为，。
例1：描述某线性时不变系统的方程为
试求：当时，系统的零状态响应。
解：实现所要求运算的m文件如下，
a = [1 4 4]; %将y（t）各阶导数的系数放在向量a中
b = [1 3]; %将f（t）各阶导数的系数放在向量b中
sys = tf(b, a); %求系统模型sys
td = ; %定义时间间隔
t = 0 : td : 10; %定义时间向量
f = exp(-t); %将f（t）表示出来
y = lsim(sys, f, t); %求系统的零状态响应
