用OpenLu（可从www.forcal.net下载）求解。 本例的难点在于微分方程拟合时要传递参数x（中间变量），这对Lu脚本来说不是问题，gsl支持的Lu扩展数学库中求解微分方程的函数gsl_ode中提供了该功能。 进一步讨论：微分方程求解传递中间变量时，按时间t的改变量进行插值，可提高求解精度。例如，进行线性插值，需传递一个数组 x4[t0,t1,x0,x1]，这样 x=x0+(x1-x0)*[(t-t0)/(t1-t0)] 。 取部分数据拟合，Lu代码： !!!using["luopt","math","win"]; //使用命名空间 f(t,y,dy,x4 : t0,t1,x0,x1,x : p1,p2)= { in[x4, 0, &t0,&t1,&x0,&x1], //取出数据 x=x0+(x1-x0)*[(t-t0)/(t1-t0)], //线性插值计算x dy=p1*y+p2*x, 0 //成功返回0 }; 目标函数(_p1,_p2 : i,s,y0,tf : tA,yA,xA,max,x4,t2,y1, p1,p2)= { p1=_p1, p2=_p2, //传递优化变量 y0=1.25664E-07, //初值 i=0, s=0, while{++i<max, SetArray{x4 : tA[i-1,0], tA[i,0], xA[i-1,0], xA[i,0]}, //准备传递数据 t2[0]=tA[i-1,0], t2[1]=tA[i,0], y1[0]=y0, //最后一个参数50表示gsl_ode函数在计算时,最多循环计算50次,这样可以提高速度 tf=gsl_ode[@f, nil, x4, t2, y1, 1e-6, 1e-6, gsl_rkf45, 1e-6,50], y0=tf(1,1), s=s+[y0-yA(i,0)]^2.0 }, s }; main(: tyArray : tA,yA,xA,max,x4,t2,y1)= { tyArray=matrix{ //存放实验数据 "0 1.25664E-07 0 0.005 0.114139113 0.156918191 0.01 0.224758442 0.31286893 0.015 0.324559128 0.466890728 0.02 0.41208094 0.618033989 0.025 0.487772126 0.765366865 0.03 0.552888138 0.907980999 0.035 0.608846185 1.044997129 0.04 0.656951948 1.175570505 0.045 0.698318143 1.298896097 0.05 0.733862018 1.414213562 0.055 0.764329017 1.520811931 0.06 0.790321332 1.618033989 0.065 0.812323879 1.705280329 0.07 0.83072574 1.782013048 0.075 0.845837104 1.847759065 0.08 0.857902342 1.902113033 0.085 0.867109907 1.944739841 0.09 0.873599694 1.975376681 0.095 0.87746832 1.993834667 0.1 0.878772672 2 " }, len[tyArray,0,&max], tA=tyArray(all:0), yA=tyArray(all:1), xA=tyArray(all:2), //用len函数取矩阵的行数，tA取矩阵的列 x4=ra1[0,0,0,0], t2=ra1[0,0], y1=ra1[0], //准备数组 Opt1[@目标函数] //Opt1函数全局优化 }; 结果： -32997.3853793671 15830.42381251212 0.1177179718140771 因模型与数据匹配不好，故效果图就不提供了，本例的意义在于微分方程拟合时如何传递中间参数。 |
