matlab中如何判断两个符号表达式是否相等?
d_t_vvhh1=d_t_hh*abs(T_vv))^2/(abs(T_hh))^2*abs(a_vv)/abs(a_hh)+d_t_vv)/(abs(T_vv)/abs(T_hh))/(abs(a_vv)/abs(a_hh)+1);
d_t_vvhh2=(d_t_vv*abs(T_hh))/abs(T_vv) + (abs(a_vv)^2*(d_t_vv*abs(T_hh)^2 - d_t_hh*abs(T_vv)^2))/(abs(T_hh)*abs(T_vv)*(abs(a_hh)^2 - abs(a_vv)^2)) - (abs(T_hh*T_vv*a_hh*a_vv)*(d_t_vv*abs(T_hh)^2 - d_t_hh*abs(T_vv)^2)*(abs(T_hh)^2*abs(a_hh)^2 + abs(T_vv)^2*abs(a_vv)^2))/(abs(T_hh)^2*abs(T_vv)^2*(abs(a_hh)^2 - abs(a_vv)^2)*(abs(T_hh*a_hh)^2 + abs(T_vv*a_vv)^2));
如何判断d_t_vvhh1是否等于d_t_vvhh2?

答案和解析
syms T_vv T_hh .
d_t_vvhh1=.
d_t_vvhh2=.
simplify(d_t_vvhh1 - d_t_vvhh2)
