 +====== Print ======
  
 +###
 +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.
 +###
 +
 +===== Options =====
 +###
 +//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" ====
 +
 +###
 +"File" of type string: A string specifying the file name to which the wavefunction is printed (over writing the old file)
 +###
 +
 +===== Example =====
 +
 +###
 +The following example creates the spectra as defined in the [[documentation:language_reference:objects:spectra:start|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.
 +###
 +
 +==== Input ====
 +<code Quanty Example.Quanty>
 +dofile("definitions.Quanty")
 +G = CreateSpectra(H, T1, psi, {{"Emin",-1}, {"Emax",11}, {"NE",12}})
 +print(G)
 +G.Print()
