matlab 优化工具箱

请各位高手麻烦看一下下面的程序，书上是这样写的，但运行一直有错，应该怎么改呢？
菜鸟急求正解
function f=y(x)
f(1)=10-0.0116*x(2)-0.0185*x(3)-0.0194*x(5)-0.0302*x(6)-0.1013*x(8)-0.0162*x(9);

显示的是??? Error using ==

在matlab命令窗口中输入:edit，然后将下列两行百分号之间的内容复制进去，保存。

返回matlab命令窗口，输入以下命令，应当就有结果了。
A=[0.042,0,0,0.07,0,0,0.0365,0,0;
0,0.043,0,0,0.072,0,0,0.0375,0;
0,0,-0.044,0,0,-0.074,0,0,-0.0385;
0,0,0.044,0,0,0.074,0,0,0.0385;
1,1,1,0,0,0,0,0,0;
0,0,0,1,1,1,0,0,0;
0,0,0,0,0,0,1,1,1];
b=[4,23,-14,16,310,310,150]';

weight=abs(goal);
lb=0;
