标题: 继前面问题求助。。。matlab,solve问题
警告: The solutions are parametrized by the symbols:
z1 = RootOf(z^4 - r*z^3 - (z^2*(- 8*r - 2*h*r + h^2*tan(arpha)^2 + h^2 + 4*r^2 + 2*h^2*tan(arpha) - 2*h*r*tan(arpha) + 4))/4 + (z*(4*r -
8*r^2 + 4*r^3))/4 - r^4/4 - r^2/4 + r^3/2, z) minus {h/2 + (h*tan(arpha))/2, r - h/2 - (h*tan(arpha))/2}

> In solve at 190
对应ans
ans =

(r*(r - 1)*(-h*(tan(arpha) + 1)*(h - 2*r + h*tan(arpha)))^(1/2))/(- r^2 + r) - r + 1
1 - (r*(r - 1)*(-h*(tan(arpha) + 1)*(h - 2*r + h*tan(arpha)))^(1/2))/(- r^2 + r) - r
(4.0*z1^3)/(r - 1.0*r^2) + (4.0*z1^2)/(r - 1.0) - (1.0*(h^2*tan(arpha)^2 + 2.0*h^2*tan(arpha) + h^2 - 2.0*h*r*tan(arpha) - 2.0*h*r + 4.0*r^2 - 8.0*r + 4.0)*z1)/(r - 1.0*r^2) - 3.0*r + 3.0
