下面是代码.我用的迭代命令[w,l]=fsolve('w_l',[1.982,2.884],optimset('display','off'))
function xuanzhixian=w_l(w,l)

p1=1-1/(tanh(0.48*(2*w/s-1)^0.5/(1+(b-s)/s)^2))
if w/s<=0.5
    zo=p2
else
    zo=p2*p1
end
zooa=z00-zo
k=tanh(293.9*d/zooa)
k1=(1-k^2)^0.5
if k^2<=0.5
    k2=pi/log(2*(1+k1^0.5)/(1-k1^0.5))
else
k2=log(2*(1+k^0.5)/(1-k^0.5))/pi
end
zoea=60*pi/k2

doo=2*pi*f0/300*(1+w*cfo*zoo/n0/eeo^0.5)*eeo^0.5
xuanzhixian2=diedai_2(zoe,zoo,deo,doo)
其中
function f(w1,l1)=diedai_1(zoe,zoo,deo,doo)
f(w1,l1)=(zoe^2+zoo^2-2*zoe*zoo*(cot(dec)*cot(doc)+csc(dec)*csc(doc)))/(2*(zoe*csc(dec)-zoo*csc(doc)))+z0/tan(pi*fc/(2*f0))
diedai_2类似
