psalsa baseline estimation

PSALSA is an algorithm designed for baseline estimation in spectral data, which modifies the original Asymmetric Least Squares (ALS) method.

PSALSA - BASELINE ESTIMATION FOR SPECTRAL DATA USING MATLAB

OVERVIEW

psalsa is an algorithm for baseline estimation in spectral data.

This set of files includes the implementation of the algorithm in MATLAB, along with a demo and test dataset

INCLUDED FILES

This set includes the following files:

• README.txt file -> a brief explanation of the package contents
• psalsa.m -> the MATLAB script function implementing the psalsa algorithm
• SynSpec.mat -> a synthetic MATLAB dataset for testing the psalsa script function
• psalsaDemo.m -> a MATLAB demo script, showing the usage of the psalsa.m script function

USAGE

To use the psalsa script function, the psalsaDemo script, and the SynSpec.mat MATLAB dataset, copy the files to a folder that is accessible to MATLAB.

Review the help of the psalsa function for detailed usage and syntax.

Review and run the psalsaDemo for a quick understanding of the performance of the psalsa script.

For a detailed explanation refer to the references listed in the help of the psalsa script function.
