For a spectrum object G, G.Print() prints the spectra G. Generally print(G) is preferred over G.Print(). G.Print() is more memory efficient and therefore useful for large objects. G.Print() returns nill and prints the spectra to standard output. Options can be specified if you want to print to file.
psi.Print() accepts options. Several options are specified as a list {} of single options. A single option is given as a list of name and value, {“name”,value}.
“File” of type string: A string specifying the file name to which the wavefunction is printed (over writing the old file)
The following example creates the spectra as defined in the definitions.Quanty file on a very coarse mesh in order to reduce the printout. It then prints the spectrum to screen using two different methods.
dofile("definitions.Quanty")
G = CreateSpectra(H, T1, psi, {{"Emin",-1}, {"Emax",11}, {"NE",12}})
print(G)
G.Print()
