The Chemometrics Toolbox provides more than 70 specialized MATLAB functions for chemometric calibration. It enables you to perform quantitative and qualitative analysis using powerful methods such as Multiple Linear Regression, Principal Component Regression, and Partial Least-Squares in latent variables. Chemometrics organizes chemical data into matrices so that it can be processed to create calibrations or extract useful information. This makes MATLAB an ideal environment for chemometrics.
