Function X = mollier_X(T, F, pb,prop);
X = mollier_X(pv,[],pb,prop);
returns the absolute humidity X of the air
(in kg of water vapour per kg of dry air) for
either:
-- the given air temperature T (in degrees C),
the given relative humidity F (with a value
of 0...1) and the given total pressure (or
barometric pressure) pb (in Pa),
or:
-- the given partial vapour pressure pv
(in Pa) and the given total pressure (or
barometric pressure) pb (in Pa).
The fourth input argument prop is a struct
containing information on humid air properties,
as returned by m-file mollier_humidairprop.m.
This function is called, if the fourth input
argument is not given.
If pb is empty or not given, the value of
prop.pbstandard is used.
If the first and second arguments are given (and
not empty), the calculation of the absolute
humidity is based on the function:
mollier_ps_....m
of which the m-file name is given by prop.ps_fun.
