Three-Dimensional Fluorescence – Parallel Factor Analysis – Quick Processing with MATLAB
1. Basic Principles Three-dimensional fluorescence spectroscopy (EEM) constructs a three-dimensional data matrix (sample×excitation wavelength×emission wavelength) by scanning the fluorescence intensity of the sample at different excitation wavelengths (Ex) and emission wavelengths (Em). Parallel factor analysis (PARAFAC) is a mathematical algorithm based on trilinear decomposition theory, which uses alternating least squares (ALS) to decompose the complex … Read more
