Fundamental physical constants

Functions that returns a struct() containing most fundamental physical constants.

The struct has two levels. The first level is the name of the constant. The second level has fields: "value", "uncert" and "unit".
Example:
phc = fundamentalPhysicalConstantsFromNIST();
phc.speed_of_light_in_vacuum.value
returns
299792458
and
phc.speed_of_light_in_vacuum.unit
returns
ms^-1
Data was obtained from http://physics.nist.gov./cuu/index.html and (almost) automatically transfered to matlab syntax with the help of some c and awk programming.

The constants who's uncertainties are given av (exact), the value of 0 is returned.
