The following are top-level functions which are used for exploratory analysis of multi-way data (data with 3 or more modes.)

Primary Multiway Tools

analysis - Graphical user interface for data analysis.
mpca - Multi-way (unfold) principal components analysis.
gram - Generalized rank annihilation method.
parafac - Parallel factor analysis for n-way arrays.
parafac2 - Parallel factor analysis for unevenly sized n-way arrays.
tld - Trilinear decomposition.
tucker - Analysis for n-way arrays.

Lower-level Multiway Utilities

outerm - Computes outer product of any number of vectors.
corcondia - Evaluates consistency of PARAFAC model.
coreanal - Analysis of the core array of a Tucker model.
corecalc - Calculate the Tucker3 core given the data array and loadings.
modelviewer - Visualization tool for multi-way models.
nassign - Generic subscript assignment indexing for n-way arrays.
nindex - Generic subscript indexing for n-way arrays.
unfoldm - Rearranges (unfolds) an augmented matrix to row vectors.
unfoldmw - Unfolds multiway arrays along specified order.
eemoutlier - Automatically remove outliers in PARAFAC models of EEM data.
