Toolbox: X-ray Refraction of Matter

A function to calculate material properties interacted with x-rays.

Description

Function REFRAC returns material properties interacted with x-rays.

refrac('Formula',energy,massdensity) gives refraction in terms of disperion(delta) and absorption(beta), as well as critical angle and attenuation length corresponding to the input energy. Also a plot of these properties is given.

For example:
>>result=refrac('Si3N4',8.04778,3.44)
result =
        formula: 'Si3N4'
    massDensity: 3.44
 eletronDensity: 1.4767e+028
         energy: 8.0478
     wavelength: 1.5406e-010
     dispersion: 1.1164e-005
     absorption: 1.6477e-007
  criticalAngle: 0.27074
      attLength: 7.4403e-005

Dear Sir,
I am getting error result=refrac('Si3N4',8.04778,3.44)
??? Error using ==> refrac
Element 'Si' is NOT in the table list.

when I am using the same example, which is default in programme itself. Please help me how to run this programme. awaiting for your reply.
