Clone

Creates a copy of the spectrum. The input G1 = G2 creates two pointers to the same object. Changing G1 will change G2. G1=Spectra.Clone(G2) will create two different objects.

Example

The following example creates a clone of G and stores this in the variable GClone. Next it sets G2 equal to G. Shifting G2 will also lead to a shift in G. GClone is independent of G.

Input

Example.Quanty
dofile("definitions.Quanty")
 
GClone = Spectra.Clone(G)
G2 = G
G2.Shift(0.5)
 
G.Print({{"file","Spectra.dat"}})
G2.Print({{"file","Spectra2.dat"}})
GClone.Print({{"file","Spectra.Clone.dat"}})
 
gnuplotScript = gnuplotHead .. [[
set output "Spectra.Clone.ps"
plot "Spectra.dat"  using 1:(-$3+8) title 'G' with lines ls  1,\
     "Spectra2.dat"  using 1:(-$3+4) title 'G2' with lines ls  2,\
     "Spectra.Clone.dat"  using 1:(-$3) title 'Gclone' with lines ls  3
]]
 
file = io.open("Spectra.Clone.gnuplot", "w")
file:write(gnuplotScript)
file:close()
 
os.execute("gnuplot Spectra.Clone.gnuplot")
os.execute("convert -density 1024 Spectra.Clone.ps -resize 1024 Spectra.Clone.png")
