It is not free. While MATLAB student licenses are affordable, the PLS Toolbox is a premium commercial product. For budget-conscious users, the MATLAB Statistics and Machine Learning Toolbox includes plsregress , but that is a bare-bones function. The PLS Toolbox offers robust PCA (handling outliers), multivariate curve resolution (MCR), and batch modeling that the core functions lack.
Understand which wavelengths drive the model. plot(model, 'loadings', [1,2]) – Identify spectral regions where the loading weights are high. matlab pls toolbox

Data analysis is often described as "80% preprocessing, 20% modeling." The MATLAB PLS Toolbox excels here. It provides a dedicated interface for preprocessing chains. Common methods included are: The PLS Toolbox offers robust PCA (handling outliers),
Furthermore, there is a learning curve. The toolbox assumes you understand latent variables. If you don’t know the difference between a score plot and a loading plot, the GUI can be intimidating. But for the analyst who does, it is liberating.
