matlab解方程组solve
syms st4 st5 st7 x y z
st6=0;
frw =[-177633/15625*st5^2/pi^2+59211/50000*st5/pi+2193/100+799/25*cos(st4)*sin(st5)+3383/100*(cos(st4)*cos(st5)*cos(st6)-sin(st4)*sin(st6))*sin(st7)+3383/100*cos(st4)*sin(st5)*cos(st7)
799/25*sin(st4)*sin(st5)+3383/100*(sin(st4)*cos(st5)*cos(st6)+cos(st4)*sin(st6))*sin(st7)+3383/100*sin(st4)*sin(st5)*cos(st7)
-799/25*cos(st5)+3383/100*sin(st5)*cos(st6)*sin(st7)-3383/100*cos(st5)*cos(st7)];
[st4 st5 st7]=solve(frw(1)-x,frw(2)-y,frw(3)-z)
怎么接不出来呢,
