my commands
bhp=100*ones(10,1);
bht=[500;500;500;500;500;300;300;300;300;300];
p= @(bhp,bhT) bhp + g*dz.*rho(bhp,bhT);
tried to validation p(bhp,bhT).*bhp + g*dz.*rho(bhp,bhT)
result ans =
1.0e+09 *

how can be i got difference result if i assume a=g*dz.*rho(bhp,bhT); a =
1.0e+07 *

b=bhp;
c=a+b
result
c =

because at the top results you are evaluating
p(bhp,bhT).*bhp + g*dz.*rho(bhp,bhT)
and at the bottom
bhp + g*dz.*rho(bhp,bhT)
This can further be proved by looking at the results and seeing the relation
100*(bottom results)+a = (top results)
Also your code is missing g and rho, maybe other variables aswell for me to run it on my Matlab to further help.
