Spectra

This tool enhances signal detection for broad-mass TOF spectra by accounting for changing peak width and providing peak-shape-dependent filtering capabilities. A set of input TOF spectra is processed to produce aligned peak list and array of corresponding signal intensities. Signal processing... Platforms: Matlab

FORTRAN code provided in Xingguo Pan's 2002 dissertation entitled "Coherent Rayleigh-Brillouin Scattering" was converted to .m and is provided here. Both s6 and s7 models are provided. The code is validated Platforms: Matlab

This program estimates the background (or baseline) of optical spectra by the polynomial minimizing a cost function. If the cost function was quadratic, the solution is the least squares estimation, which is not appropriate in this problem. Instead, we need to use of non-quadratic cost function...
