matlab求解方程组的解析jie

syms a b c m r z k seq1 = r-s*sin(b-m)/sin(b-c);eq2 = r-a*sin(b-m)/sin(m-c);eq3 = k-z*sin(b-c)/a;[a b c] = solve(eq1,eq2,eq3,'a','b','c');

Answer 1

>> f=[2;3];
A=[-1 -1;-1 0;2 1];
b=[-350;-100;600];
[x,feval]=linprog(f,A,b,[],[],[],[])
Optimization terminated.

x =

250.0000
100.0000

feval =

800.0000

麻烦请问一下，怎么求那三个方程组的解析解
