lsqcurvefit在matlab中拟合多元函数问题这是M文件：function F=myfun(x,data)F=x(1)+x(2)*xdata(:,1)+x(3)*xdata(:,1).^2+x(4)*xdata(:,2)+x(5)*data(:,2).^2;下面是数据：xdata=[14.9,0.8;13.6,0.62;13.6,0.98;16.2,0.98;16.2,0.62];ydata=[11172
lsqcurvefit在matlab中拟合多元函数问题
这是M文件：
function F=myfun(x,data)
F=x(1)+x(2)*xdata(:,1)+x(3)*xdata(:,1).^2+x(4)*xdata(:,2)+x(5)*data(:,2).^2;
下面是数据：
xdata=[14.9,0.8;13.6,0.62;13.6,0.98;16.2,0.98;16.2,0.62];
ydata=[111729.4346 111742.47 111742.4947 111738.3368 111738.2256];
x0=[10,1]
[x,resnorm]=lsqcurvefit(@myfun,x0,xdata,ydata)
提示错误：function F=myfun(x,data)
