两方程K0*d=arctan(P0/K0)+acrtan(Q0/K0)
K1*d=arctan(P1/K1)+acrtan(Q1/K1)
已知P0= (2*3.14)/(630*((1.6223*1.6223-1.51*1.51)^0.5));
Q0=(2*3.14)/(630*((1.6223*1.6223-1)^0.5));
P1= (2*3.14)/(630*((1.6185*1.6185-1.51*1.51)^0.5));
Q1=(2*3.14)/(630*((1.6185*1.6185-1)^0.5));
K0=(a0/(630*(n1^2-b0))^0.5))
K1=(a0/(630*(n1^2-b1))^0.5))
a0=(2*3.14);
b0=1.6223*1.6223;
b1=1.6185*1.6185;
求n1和d？
用哪个matlab函数求n1和d？我用solve求解，显示无解...
请帮忙~谢谢了~
