Re: "nonconformant" error

[Robert A. Macy]

P=Pw+(8.24493*e-1-4.0899*e-3*T+7.6438*e-5*T.^2-8.2467*e-7*T.^3+5.3875*e-9*T.^4)*S+(-5.72466*e-3+1.0227*e-4*T-1.6546*e-6*T^2)


??  

DO NOT PUT THE ASTERISK BEFORE YOUR e's

else they will calculate completely differently 

Not 8.24493*e-1
but 8.24493e-1
