Purpose
Wrapper for baselining functions.
Synopsis
- [baselined_data,baselines] = baselineds(spec,options); %Calibrate and apply.
- spec = baselineds(baselined_data,baselines); %Undo
Description
Wrapper for baselining functions.
Inputs
- spec = M by N matrix of data to be baslined (class "double" or "dataset").
Options
options = a structure array with the following fields:
- plots : [ {'none'} | 'final' ] governs plotting.
- algorithm : [ {'wlsbaseline'} | 'baseline' | 'whittaker' | 'datafit']
- wlsbaseline - Baseline subtraction using iterative asymmetric least squares algorithm.
- baseline - Subtracts a polynomial baseline offset from spectra.
- whittaker - Baseline subtraction using Whittaker filter.
- datafit - Asymmetric least squares baselining.
- order : positive integer for polynomial order {default =1}.
- wlsbaseline_options : see wlsbaseline.m.
- whittaker_options : see wlsbaseline.m.
- baseline_freqs : wavenumber or frequency axis vector, see baseline.m.
- baseline_range : baseline regions, see baseline.m.
- baseline_options : see baseline.m.
- datafit_options : see datafit_engine.m. NOTE: 'lambdas' and 'trbflag' options have defaults updated for baselining.
Outputs
- baselined_data = data with baseline removed.
- baselines = baselines removed from data.
