错误是脚本文件里不能定义函数，更改如下：
%求解文件
function solvefile
x0 = [0,0,0,0,0,0,0,0,0,1]; % Make a starting guess at the solution
options = optimset('LargeScale','off');
[x, fval] = fmincon(@objfun,x0,[],[],[],[],[],[],@confun,options)
function f =objfun(x)
f =0.1*(3600*x(1)+3600*x(2)+3600*x(3)+3600*x(4)+3600*sqrt(2)*x(5)+3600*sqrt(2)*x(6)+3600*sqrt(2)*x(7)+3600*sqrt(2)*x(8)+3600*x(9)+3600*x(10));
