Simulink仿真时Embedded MATLAB Function模块中的程序如下：

1. function F = myfun(Alpha_2,Omega_2,Omega_3,Omega_4,Theta_2,Theta_3,Theta_4)
   
2. Alpha_2=0;
   
3. global rs(1) rs(2) rs(3) rs(4)
   
4. rs(1)=304.8;
   
5. rs(2)=101.6;
   
6. rs(3)=254.0;
   
7. rs(4)=177.8;
   
8. F(1)=rs(3)*(Alpha_3)*cos(Theta_3)--rs(4)*(Alpha_4)*cos(Theta_4)-rs(2)*(Omega_2)^2*sin(Theta_2)-rs(3)*(Omega_3)^2*sin(Theta_3)+rs(4)*(Omega_4)^2*sin(Theta_4);
   
9. F(2)=rs(3)*(Alpha_3)*sin(Theta_3)--rs(4)*(Alpha_4)*sin(Theta_4)+rs(2)*(Omega_2)^2*cos(Theta_2)+rs(3)*(Omega_3)^2*cos(Theta_3)-rs(4)*(Omega_4)^2*cos(Theta_4);
   
10. F=[F(1),F(2)];
    
11. [Alpha_3 Alpha_4]=fsolve('myun',optimset('Display','off'))

复制代码

运行时产生错误：
Parse: Unbalanced or misused parentheses or brackets.

Function 'myfun' (#30.96.97), line 3, column 10:
"("
Parsing failed.

Function 'myfun' (#30.0.0), line 0, column 0:

Errors occurred during parsing of Embedded MATLAB function 'myfun'(#30)

麻烦哪位大侠能帮忙改一下！！！谢谢了！！！！！！！

你把这段代码，放到一个M文件里面，初始化一个输入，调试一下。多看看提示！好像是少括号不对称了
