请求MATLAB解方程高手：MATLAB解超越方程,详情见问题补充.
方程：
f=4*((z1-hatx+xt1)^2+((hatx-xt1)*cotd(at))^2-C1)^0.5+((A2-xt1)^2-C2)^0.5-D=0
其中：
z1 = 20;
z2 = 80;
hatx = 1;
at = 20;
at1= [at-5:0.1:at+15];
A2 = (z1+z2)*cosd(at)/cosd(at1)+2*hatx-z1;
C1 = (z1*cosd(at))^2;
C2 = (z2*cosd(at))^2;
D = (z1+z2)*cosd(at)*tand(at1);
要求：
求at1= [at-5:0.1:at+15]时方程f(x)=0的所以解,并将其赋给数组x1.
得到满意答案后我会再加奖全分,
只要实数解。
