求解符号方程,要求abc关于xyz的方程,怎么求? syms a b c d=[1 0 0]; e=[x-1.1 y z]; f=[a-x b-y c-z]; f1=(a-x)^2+(b-y)^2+(c-z)^2-1; f2=cross(d,f); f3=cross(f,e); [a,b,c]=solve(f1,f2,f3)
输入报错啊 Warning: 7 equations in 3 variables. Warning: Explicit solution could not be found. > In solve at 81 In xyzzuobiao at 12 a = [ empty sym ] b = [] c = []
