matlab中为什么solve解方程时解中含有待求的未知数?
symsXaYam1n1F1H1m2n2[m2,n2]=solve((m2-m1)^2+(n2-n1)^2-F1H1^2,...((Xa-m1)*(m2-m1)+(Ya-...
syms Xa Ya m1 n1 F1H1 m2 n2[m2,n2]=solve((m2-m1)^2+(n2-n1)^2-F1H1^2,... ((Xa-m1)*(m2-m1)+(Ya-n1)*(n2-n1))/(sqrt((Xa-m1)^2+(Ya-n1)^2)*sqrt((m2-m1)^2+(n2-n1)^2))-1);subs([m2,n2],{Xa Ya m1 n1 F1H1},{146 353 -303.60937808719677128737719835232 180.41580413077680071997611341372 7.1507})就是这段程序!
