说明: 寻找三次样条多项式需要求解大量的线性方程。实际上,给定N个断点,就要寻找N-1个三次多项式,每个多项式有4个未知系数。这样,所求解的方程组包含有4*(N-1)个未知数。把每个三次多项式列成特殊形式,并且运用各种约束,通过求解N个具有N个未知系数的方程组,就能确定三次多项式。
(find cubic spline solving polynomial need a lot of linear equations. In fact, given N breakpoints, it is necessary to look for N-1 cubic polynomial, each with four polynomial coefficients unknown. Thus, by solving the equations contain 4* (N-1) unknown. Each cubic polynomial Timing special form, and use of various constraints, by solving N with N unknown coefficient equations, we can identify three polynomial.)

LISANSHIJIAN
(1) 自行设计产生两个离散序列信号,对其进行相加、乘及卷积运算。
(2) 利用filter命令求下面LTI系统的冲激响应:
y(n)-0.7y(n-1)-0.6y(n-2) + y(n-3) = x(n) + 0.5x(n-1)
(3) 画出系统的零极点图,判断系统的稳定性、因果性。
(4) 绘出系统的频响曲线。(lisan time signal analyse )
