求帮跑一次1stOpt！版本太低，跑不动sharedmodel
本帖最后由 abmdj306 于 2010-10-30 16:04 编辑小弟我最近遇到一个问题，需要对两组数据进行拟合，并且两个方程共享参数，前段时间版主已经帮我跑过一次，但是那次给的数据太少，后面的误差太大，没办法只有再来求助了，再次感谢热心的版主！以下是编写的1stOpt代码：
Title "Type your title here";
Parameters c0,a(1:2),t(1:2),m(1:2);
SharedModel;
Variable m,e1,e2;
Function e1 = c0+(a1*m^2*(m^2-m1^2)/((m^2-m1^2)^2+(t1*m)^2)+a2*m^2*(m^2-m2^2)/((m^2-m2^2)^2+(t2*m)^2));
Function e2 = a1*m^2*t1*m/((m^2-m1^2)^2+(t1*m)^2)+a2*m^2*t2*m/((m^2-m2^2)^2+(t2*m)^2);
