y: [2*1 sym] % 这意味着x和y均有两个解。函数输出的solution是一个struct,访问方法和C语言访问struct成员一样: struct.x % 命令行输入 ans = % 命令行输出 (3*2^(1/2))/2 -(3*2^(1/2))/2 1. 2. 3. 4. 5. 6. 7. 8.
Y = solve(eqns,vars,Name=Value) uses additional options specified by one or more Name=Value arguments. example [y1,...,yN] = solve(eqns,vars) solves the system of equations eqns for the variables vars. The solutions are assigned to the variables y1,...,yN. If you do not specify the...
