Detection of Water Contamination Events Using Fluorescence Spectroscopy and Alternating Trilinear Decomposition Algorithm

Figure 2

Graphical representation of trilinear model of three-way data array X. X is the original three-dimensional data matrix, and it can be decomposed to three matrices. A, B, and C are, respectively, the relative excitation matrix, relative emission matrix, and relative concentration matrix. Matrix E is the three-dimensional residual matrix.
