差分方程求解

实验步骤：

主界面下进入实验五的“差分方程求解”子系统,输入希望看到的输出样点数

1)　　输入差分方程系数向量

输入顺序为： ， 。其中 N+1 为差分方程两边系数最大数目，如果有一边输入系数个数小于 N+1，将按不足系数为零计算。

2)　　输入系统初始状态向量

输入顺序为

鼠标单击确定按钮，以数值和图形两种方式显示单位冲激响应和输出响应

3） 确定差分方程形式：y(k)-y(k-1)+0.35y(k-2)=2x(k)-x(k-1)，

-Differential equation



Experimental steps:



Five main interface into the experiment a "differential equation" subsystem, enter to see the output sample points



1) Input coefficient vector differential equation



Enter the following order:,. N+1 differential equations in which both sides of the coefficient for the maximum number, if one side is the number of input factors is less than N+1, will be less than zero coefficient calculation.



2) Enter the initial system state vector
