h=(a.*Pmin.^2+b.*Pmin+c)./(d.*Pmax.^2+e.*Pmax+f);

E=diag(((a+h.*d)./lambda)+B);

D=0.5*(1-((b+h.*e)./lambda)-B0);

P=E\D;

any body please assist me to solve P .

To over come the matlab error rdivider and matlab plus and minus error due to the vectors assigned in the above code are different length

[Yao Li]

The length of lambda is different with the length of other arrays.

There is no way to "overcome" this "problem". Elementwise operations are simply not defined for arrays of different size (except if one of them is a scalar). What do you expect when you dive an [1 x N] vector elementwise by an [1 x M] vector with N~=M ?!
