matlab求解超越方程
a=[0 0.1 0.2 0.5 1.0 2.0];
b=[0.2 0.4 0.6 0.8];
c=[0.1 0.2 0.3 0.4 0.5];
d=[0.06 0.08 0.1 0.15 0.2 0.25 0.3 0.4 0.5 0.6];
e((i-1)*6+(j-1)*4+(k-1)*5+l)=(b(j)*c(k)*d(l))^0.5;
,要求的函数1-d(l)*e((i-1)*6+(j-1)*4+(k-1)*5+l)*tan(pi/w*e((i-1)*6+(j-1)*4+(k-1)*5+l))*tan(pi/w)+6*w*a(i)/pi/e((i-1)*6+(j-1)*4+(k-1)*5+l)*tan(pi/w*e((i-1)*6+(j-1)*4+(k-1)*5+l))+ 6*w* a(i)*d(l)/pi*tan(pi/w)=0
根据不同的a b c d w在0-10的解
实际的函数是1-d*e*tan(pi/w*e)*tan(pi/w)+6*w*a/pi/e*tan(pi/w*e+ 6*w*a*d/pi*tan(pi/w)=0
其中e=（b*c*d）^0.5
