Syntax
out = sw_converter(value, unitIn, unitOut)
out = sw_converter(value, unitIn, unitOut, particleName)
Description
out = sw_converter(value, unitin, unitout) will convert momentum and
energy values assuming neutron as a particle.
out = sw_converter(value, unitin, unitout,particleName) will convert
momentum and energy values for a given particle, such as neutron, photon,
etc.
Example
Calculate the energy of a neutron (in meV) which has a wavelength of 5 Å:
sw_converter(5,'A','meV')
Output
3.2722
Calculate the wavelength of X-ray in Å that has 7.5 keV energy:
sw_converter(7.5,'keV','A','photon')
Output
1.6531
Input Arguments
