The toolbox extends MATLAB's core functionality with over 300 specialized tools and interfaces.
Raw data is rarely ready for direct modeling. The analysis interface includes a sophisticated panel where you can apply a sequence of filters. A typical workflow for NIR spectra might involve applying a Savitzky-Golay derivative (to remove baseline shifts) followed by Standard Normal Variate (SNV) normalization (to correct for scatter effects).
While the GUIs provide an accessible starting point, the true power of the PLS_Toolbox is unlocked through scripting at the MATLAB command line. Scripting allows for the automation of repetitive tasks, easy handling of updates, and superior documentation of the entire analysis workflow. The evriinstall script ensures the command-line functions are fully integrated and available. Eigenvector Research and its partners offer comprehensive training courses, from introductions to scripting and customized on-site training, to help users transition from clicking buttons to writing efficient, reproducible scripts.
Features automated toolsets for multiplicative scatter correction (MSC), standard normal variate (SNV), Savitzky-Golay filtering, and baseline detrending.
