INDAFAC (INcomplete DAta paraFAC) is a sparse Levenberg-Marquardt algorithm for fitting PARAFAC to three-way arrays with missing data. Supports multiple convergence criteria and initialization methods (random, SVD/NIPALS, DTLD/GRAM). Includes CreaMiss.m for generating synthetic incomplete arrays. The companion PARAFAC3W package provides Levenberg-Marquardt, ALS, SWATLD, and PMF3 algorithms with optional compression.
