What is the difference between scalar and vector functions?

Hi all :)

can anybody help me out in understanding scalar function

and vector function?

the difference between them

 

[Char. Limit]

A function gives a scalar field if the output of the function is a scalar, or a single number. A function gives a vector field if the output of the function is a vector.

that means thermodynamic potentials like gibbs energy = scalar function

further if u=h+pv that s enthalpy

how could it be sol to scalar function? can you elaborate its please
