Hi!!
Im trying to resolve this equation, but im getting this error:
octave:17> P=Pw+(8.24493*(10^-1)-4.0899*(10^-3)*T+7.6438*(10^-5)*T.^2-8.2467*(10^-7)*T.^3+5.3875*(10^-9)*T.^4)*S+(-5.72466*(10^-3)+1.0227*(10^-4)*T-1.6546*(10^-6)*T^2)*S.^(3/2)+4.8314*(10^-4)*S.^2;
error: operator *: nonconformant arguments (op1 is 1x421, op2 is 1x211)

error: evaluating binary operator `+' near line 17, column 102
error: evaluating binary operator `+' near line 17, column 166

I revised all terms but couldn't find any problem with it...
Can someone lend me a hand??
Thanks!
