Matlab解三角函数方程组

波波球

syms f x y z tx ty tz a b
Y =[
189/50*f*cos(y)*cos(z)*a-189/50*f*cos(y)*sin(z)*b+189/50*f*tx
189/50*f*(sin(x)*sin(y)*cos(z)+cos(x)*sin(z))*a+189/50*f*(-sin(x)*sin(y)*sin(z)+cos(x)*cos(z))*b+189/50*f*ty
(cos(x)*sin(y)*cos(z)+sin(x)*sin(z))*a+(-cos(x)*sin(y)*sin(z)+sin(x)*cos(z))*b+tz
];
Y是三行一列
我想求解Y=0时用其他符号表示x,y,z，该如何解？用solve很慢！

没办法，符号解本来就慢
