Question

求大神帮用matlab解方程组方程如下:W0(1+(Z1/Z0)^2)^0.5=1.669e-3W0(1+(Z2/Z0)

Answer 1

%x(1)=z0 x(2)=z1 x(3)=z2 x(4)=w0

f=@(x)[x(4).*sqrt(1+(x(2)./x(1)).^2)-1.669e-3

x(4).*sqrt(1+(x(3)./x(1)).^2)-3.38e-3

x(3)-x(2)-0.1

x(4)-sqrt(3.37e-6*x(1))];

fsolve(f,[0.1 0.1 0.2 0])

Optimization terminated:first-order optimality is less than options.TolFun.

ans =

0.01143253271003 0.09653672599277 0.19653672599277 0.00019628480133

所以

z0=0.01143253271003

z1=0.09653672599277

z2=0.19653672599277

w0=0.00019628480133
