Content

This repository contains all the code and data files to reproduce the paper "A pseudo-Voigt component model for high-resolution recovery of constituent spectra in Raman spectroscopy". The main contribution of the paper namely a source seperation using a pseudo-Voigt component model is implemented in the file gibbsvoigt.m

Reproduction

Simulations and figures has been created with Matlab 2016a on Windows10 64bit. To reproduce the paper figures and pdf open a terminal and use

# make clean all

The makefile has been tested on Ubuntu linux and on windows 10 bash build 1607. Previous builds of windows 10 bash are not supported by the makefile. Mac OS should work as well. The makefile makes use of pdfcrop so make sure that is installed. This is found in the debian package texlive-extra-utils.

The simulations are not reproduced by the makefile. These can be reproduced by running the two matlab scripts manually

>> run_nmf
>> run_voigt

The corresponding mat files will not be 100% identical since the mat files are a result of a simuation. Even with the random number generator started the same way, the operating system and versions of software libraries will alter the results slightly.
