求助！三個(gè)未知數(shù) 四個(gè)方程用1stopt(Anto2Fit)約束優(yōu)化 已有2人參與

計(jì)算小白，新來的沒啥金幣 用的Anto2Fit 5.5試用版（明明三個(gè)parameters為啥說超出四個(gè)了） 方程都比較長 不知道為什么三個(gè)未知數(shù)會出現(xiàn)四個(gè)結(jié)果 第四個(gè)結(jié)果好像是我給的常數(shù)變量或者變參量（偷梁換柱？） 貼上mathematica里寫的表達(dá)式（這個(gè)軟件里運(yùn)行過三個(gè)方程三個(gè)變量的求解，方程本身沒問題） Constant cc = 3*10^8; la = cc/10^9; k0 = 2*pi/la; r1 =0.17532; r2 =0.21216; t1 =0.77139; t2 =-0.3507; Parameter k1[30,60],k2[-2,0],dz[0.5,0.7]; Function a=sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz)); b=cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz)); c=cos(k1*dz)*(exp(-k2*dz)+exp(k2*dz)); d=sin(k1*dz)*(exp(-k2*dz)-exp(k2*dz)); kk=2*(k1^2+k2^2); (r1*c)-(r2*d)+r1*(b*k1-a*k2)/(2*k0)+r1*(a*k0*k2+b*k0*k1)/kk-r2*(a*k1+b*k2)/(2*k0)-r2*(a*k0*k1-b*k0*k2)/kk-(b*k1-a*k2)/(2*k0)+(a*k0*k2+b*k0*k1)/kk; (r2*c)+(r1*d)+r1*(a*k1+b*k2)/(2*k0)+r1*(a*k0*k1-b*k0*k2)/kk+r2*(b*k1-a*k2)/(2*k0)+r2*(a*k0*k2+b*k0*k1)/kk-(a*k1+b*k2)/(2*k0)-(b*k0*k2-a*k0*k1)/kk; (t1*c)-(t2*d)+t1*(b*k1-a*k2)/(2*k0)+t1*(a*k0*k2+b*k0*k1)/kk-t2*(a*k1+b*k2)/(2*k0)-t2*(a*k0*k1-b*k0*k2)/kk+2; (t2*c)+(t1*d)+t1*(a*k1+b*k2)/(2*k0)+t1*(a*k0*k1-b*k0*k2)/kk+t2*(b*k1-a*k2)/(2*k0)+t2*(a*k0*k2+b*k0*k1)/kk; //方程我用了兩種寫法第二種太長了 Function (r1*cos(k1*dz)*(exp(-k2*dz)+exp(k2*dz)))-(r2*sin(k1*dz)*(exp(-k2*dz)-exp(k2*dz)))+r1*(cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k1-sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k2)/(2*k0)+r1*(sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k0*k2+cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k0*k1)/2*(k1^2+k2^2)-r2*(sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k1+cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k2)/(2*k0)-r2*(sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k0*k1-cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k0*k2)/2*(k1^2+k2^2)-(cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k1-sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k2)/(2*k0)+(sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k0*k2+cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k0*k1)/2*(k1^2+k2^2); (r2*cos(k1*dz)*(exp(-k2*dz)+exp(k2*dz)))+(r1*sin(k1*dz)*(exp(-k2*dz)-exp(k2*dz)))+r1*(sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k1+cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k2)/(2*k0)+r1*(sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k0*k1-cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k0*k2)/2*(k1^2+k2^2)+r2*(cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k1-sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k2)/(2*k0)+r2*(sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k0*k2+cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k0*k1)/2*(k1^2+k2^2)-(sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k1+cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k2)/(2*k0)-(cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k0*k2-sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k0*k1)/2*(k1^2+k2^2); (t1*cos(k1*dz)*(exp(-k2*dz)+exp(k2*dz)))-(t2*sin(k1*dz)*(exp(-k2*dz)-exp(k2*dz)))+t1*(cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k1-sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k2)/(2*k0)+t1*(sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k0*k2+cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k0*k1)/2*(k1^2+k2^2)-t2*(sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k1+cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k2)/(2*k0)-t2*(sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k0*k1-cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k0*k2)/2*(k1^2+k2^2)+2; (t2*cos(k1*dz)*(exp(-k2*dz)+exp(k2*dz)))+(t1*sin(k1*dz)*(exp(-k2*dz)-exp(k2*dz)))+t1*(sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k1+cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k2)/(2*k0)+t1*(sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k0*k1-cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k0*k2)/2*(k1^2+k2^2)+t2*(cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k1-sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k2)/(2*k0)+t2*(sin(k1*dz)*(exp(-k2*dz)+exp(k2*dz))*k0*k2+cos(k1*dz)*(exp(-k2*dz)-exp(k2*dz))*k0*k1)/2*(k1^2+k2^2); 22.JPG@月只藍(lán) |
