在MATLAB中遇到缺少算子问题，求指教

fun=’[-20*x(1)-37*x(2),-3x(1)-8*x(2)]’;
a= [2,1;
1,2];
b= [30,24]’;
lb= [0,0];
goal=[-500,-96];
weight=abs(goal);
x0=[7,7];
[x,fval,attainfactor,exitflag]=fgoalattain(fun,x,goal,weight,a,b,[],[],lb,[])

结果提示：
??? Error using ==> inlineeval
Error in inline expression ==> [-20*x(1)-37*x(2),-3x(1)-8*x(2)]
??? Error: Missing MATLAB operator.

Error in ==> inline.feval at 34 INLINE_OUT_ = inlineeval(INLINE_INPUTS_, INLINE_OBJ_.inputExpr, INLINE_OBJ_.expr);
Error in ==> fgoalattain at 282
user_f = feval(funfcn{3},x,varargin{:});

请问问这是怎么一回事，怎么解决，谢谢啦~

fun里面缺少乘号，修改如下
fun='[-20*x(1)-37*x(2),-3*x(1)-8*x(2)]';

支持一下感觉挺不错的
