用OpenLu（可從www.forcal.net下載）求解。
Lu代碼：

!!!using["luopt","math","win"]; //使用命名空間

y(yibxilong_infite,yibxilong_s,tao,bet_a,Omega)= yibxilong_infite+((yibxilong_s-yibxilong_infite)/((1+1i*Omega*tao)^bet_a));

目標(biāo)函數(shù)(yibxilong_infite,yibxilong_s,tao,bet_a : i,s, e11,e22 : max, f, e1, e2)=
{
i=-1, s=0, while{++i<max, toreal[y(yibxilong_infite,yibxilong_s,tao,bet_a,f(i,0)), &e11,&e22], s=s+[e1(i,0)-e11]^2+[e2(i,0)-e22]^2 },
s
};

main(: tArray : max, f, e1, e2)=
{
tArray=matrix{ //存放實(shí)驗(yàn)數(shù)據(jù) //f e1[realPart] e2[imagPart]
      "2       4.37523       0.62119
2.08       4.33845       0.62521
。。。省略數(shù)據(jù)
17.92       2.82796       1.7813"
},
len[tArray,0,&max], f=tArray(all:0), e1=tArray(all:1),e2=tArray(all:2), //用len函數(shù)取矩陣的行數(shù)，f等取矩陣的列
Opt1[@目標(biāo)函數(shù)] //Opt1函數(shù)全局優(yōu)化
};

結(jié)果：

4.169983461876345 3.956371175465695 0.1605626263979209 -0.7356730581825803 23.18657063877461

似乎模型與數(shù)據(jù)不匹配。

擬合參數(shù)：yibxilong_infite,yibxilong_s,tao,bet_a -- 當(dāng)作復(fù)數(shù)，匹配度有所提高。
