Datafiles for testing are available in TDALAB benchmark [~30MB].

Tensor Toolbox (TDALAB) provides fundamental data structures and functions for tensor data processing. TDALAB attempts to provide an easy to use, user-friendly toolbox for experimentation and application of tensor decomposition and analysis.

• friendly graphical user interface (GUI) for tensor decompositions, enabling easy selection of decomposition model, algorithm, and parameters
• platform for comparison and evaluation of a large number of state-of-the-art tensor decomposition algorithms, and provides friendly GUI to access the widely used functions included in N-way Toolbox and Tensor Toolbox, and some of the latest developments in tensor decompositions.
• implementation of constrained tensor decomposition by incorporating standard 2D Penalized Matrix Factorization (PMF) methods in order to impose diversity/constraints on components (columns of factor matrices), such as orthogonality, statistical independence, sparsity, nonnegativity, etc (as in Multilinear Blind Source Separation (MBSS)).
• implementation of 2D constrained matrix factorization (also referred to as 2D Blind Source Separation (BSS))
• multiple visualization approaches for tensor objects are provided, users can explore the components and their connections
