Rolling ball

Description

Ideas from Rolling Ball algorithm for X-ray spectra by M.A.Kneen and H.J. Annegarn. Variable window width has been left out

Usage

baseline.rollingBall(spectra, wm, ws)

Arguments

`spectra`	Matrix with spectra in rows
`wm`	Width of local window for minimization/maximization
`ws`	Width of local window for smoothing

Value

`baseline`	Matrix of baselines corresponding to spectra `spectra`
`corrected`	Matrix of baseline corrected spectra
