matlab求联立方程，大侠们进来看下！！！

你还是老老实实将数值代人方程里，再用solve求解。因为变量愈多，他就会糊里糊涂，容易出错。
s =
a: [1x1 sym]
f1: [1x1 sym]
f2: [1x1 sym]
t: [1x1 sym]
>> s.a
ans =
29.25748919113280194998392607727
>> s.f1
ans =
-5099.5059281938833746138593856386
>> s.f2
ans =
-4528.8488558904105895173945946402
>> s.t
ans =
-89.499122997216732329202890631791追问我把数值带进去，确实不报错了，但算不出答案。你那
s =
a: [1x1 sym]
f1: [1x1 sym]
f2: [1x1 sym]
t: [1x1 sym]

程序里要写入这个吗追答这是计算得出的结果。

正好在用MATLAB，就拷进去试了一下，可以运行啊，没提示出错，不过算了一会了还没好追问我的咋一直提示出错Warning: Explicit solution could not be found.

s=[s.f1 s.f2 s.a s.t];追答感觉你在解圆锥曲线的方程？如果你装了Mathematics可以试一下，我这边还没算好呢
Explicit solution could not be found是没有解析解的意思，你定义的是符号变量，可能算起来很慢，改成数值变量试试？追问确实是圆锥曲线，椭圆与双曲线相切，应该有四个解才对啊，但为什么只输出一个解。
