三个问题：
1：Z1是实部值还是虚部值？
2：参数Z0,m,t,c都是实数？或是复数？
3：公式“ Z1=Z0*(1-m*(1-1/(1+(i*6.28*t)^c)));”根本没出现自变量f，正确吗？
Z1是复数，测出来的Z1是模值，参数都是实数，大神在用下面的试一下吧，为什么我用1stopt1.5就算不了下面的呢
Title "Type your title here";
Parameters Z0,m[0,1],t,c[0,1];
Variable f,Z1;
Function Z1=Z0*((1+2*(1-m)*((6.28*f*t)^c)*cos(3.14*c/2)+((1-m)^2)*(6.28*f*t)^(2*c))/(1+(2*(6.28*f*t)^c)*cos(3.14*c/2)+(6.28*f*t)^(2*c)))^(1/2);
date;
//f,Z1;
