Interactive MATLAB interface for masking Rayleigh and Raman scatter in EEM fluorescence data and handling masked pixels with NaN, interpolation, SVD, PARAFAC-ALS, O-ALS, or MCR-ALS.
A Whittaker smoother using penalized LS & iterative imputation to smooth data & fill gaps.
NIPALS performs PCA on data using iterative least squares and deflation steps. It can deal with missing values.
Sparse PARAFAC fitting for incomplete multi-way data via Levenberg-Marquardt
Iterative SVD performs iterative PCA-based imputation to handle missing data.
OALS calculates the scores and loadings from data with missing values.
This code recovers saturated signals using O-ALS by treating saturated signal as NaNs and reconstructing them from PCA subspace.
