急求matlab syms
syms x y
equ=(x-rl/(1+rl)).^2 + y.^2 -(1/(1+rl)^2);
equ1=(x-1).^2+(y-1/xl).^2-(1/xl)^2';
[x,y]=solve(equ,equ1);
t=x(2,:);m=y(2,:);
plot(double(t),double(m),'r*');
Undefined function or method 'syms' for input arguments of type 'char'.
但如果去掉syms时
有出现?Undefined function or variable "x".这到底是怎么回事?要怎么解决呢?
之前已经定义啦xl,rl啦,出现问题1,是在gui里运行出的警告,是怎么回事呢?gui运行出问题,生成的,exe就无法运行啦!

还是把全部的发来我给你调吧．你贴出来的不完整．
