Tools for the decomposition of tensors

Tensor Toolbox provides functionalities for the decomposition of tensors in tensor-train format [1] and spectral tensor-train format [2].

The toolbox provides the following tools:

    TT-svd
    TT-cross
    TT-vectors
    TT-matrices
    Quatics TT-vectors/matrices
    TT-integration
    Basic operations in TT format
    Multi-linear algebra in TT format (Steepest descent, CG and GMRES)
    STT-construction
    STT-projection/interpolation
    STT for single quantities and for fields
