Would you have Matlab packege to calculate Lorentz number from measured value of Seebeck coefficieny?

I want to use the Fermi-Dirac integral (contained in the zipped files) for calculation of Lorentz number from measured value of Seebeck Coefficient.

But I didn't understand why only shortcut is given for the three MS access tables (FDtable, Fjx & Fdeg).

Would you mind to help me please?

Sincerely

Endale
