Tensor-class function

S4 Class for a Tensor

An S4 class for a tensor with arbitrary number of modes. The Tensor class extends the base "array" class to include additional tensor manipulation (folding, unfolding, reshaping, subsetting) as well as a formal class definition that enables more explicit tensor algebra. class

Note

All of the decompositions and regression models in this package require a Tensor input.

Slots

• num_modes: number of modes (integer)
• modes: vector of modes (integer), aka sizes/extents/dimensions
• data: actual data of the tensor, which can be 'array' or 'vector'
