I have a raman spectrum that look like this:
The x-axis is in wavenumber. How do I convert it to wavelength.
The wavenumber and wavelength relation is govern by:
w = the wavenumber
λ0 = excitation wavelength, which is 785nm in this case
λ1 = the Raman spectrum wavelength, which i want to obtain in this case
The wavenumber are:

when you do your plot, instead of plotting all your y data against wavenumber, just plot against wavelength
plot(wavenumber,[y1,..,yn]) -> plot(wavelength,[y1,..,yn])
Or if you want to change the figure already created, you need to modify the Xdata property of all your plot with a command looking like
set(findall(gca,'Type','line'),'Xdata',wavelength)
where wavelength is the new vector you just calculated, which has the same size as wavenumber.
