我一眼看不出来，但是你的题目对matlab来讲太简单
- clear all;
- clc;
- syms r1 r2 r3 c1 c2 c3 s
- pz=@(z1,z2) z1*z2/(z1+z2) %阻抗并联规则
- sz=@(z1,z2) (z1+z2) %阻抗串联规则
- Zg=pz(r1,sz(r3,1/s/c2))
- Zf=pz(1/s/c3,sz(r2,1/s/c1))
- hs=collect(Zf/Zg,s)
- [num,den]=numden(hs)
- Z=simple(solve(num,s))
- P=simple(solve(den,s))
- Z =
-
- -1/(c2*(r1 + r3))
- -1/(c1*r2)
-
-
- P =
-
- 0
- -1/(c2*r3)
- -(c1 + c3)/(c1*c3*r2)
