Tk=T+273.15;
for i=1:4
    Ki(i)=exp(Ai(i)-Bi(i)./(Ci(i)+Tk))/Patm;
end
Ki(4)=exp(Ai(4)-Bi(4)./(Ci(4)+Tk))/Patm*760/101.3
sum1=0.;
for i=1:4
    num=z(i).*(Ki(i)-1);
    denom=1+(Ki(i)-1)*v;
    sum1=sum1+num./denom;
end
y=sum1;
上述的函数是求 v的,Matlab显示的错误如下
???  In an assignment  A(I) = B, the number of elements in B and
I must be the same.

Error in ==> Profit at 34
    Ki(i)=exp(Ai(i)-Bi(i)./(Ci(i)+Tk))/Patm;
求高手帮帮啊,我在线等
