>> Working with Tensors

- Multiplying Tensors -
Covers many types of tensor multiplication including
`ttv`, `ttm`, `ttt`, `mttkrp`,
`innerprod`, `contract`, `norm`
- Mode-n Vectors - Generating
the leading mode-n vectors using
`nvecs`
- Collapsing and Scaling
Tensors - Computing sums, means, mins, maxs, and so on for
portions of the tensor and conversely scaling portions of the
tensor.
- Converting Between Tensors and
Matrices - Convert between tensors and matrices, both
dense and sparse.
- Creating Test
Problems - Covers
`create_problem`
and `create_guess` for generating test random
problems with specified characteristics
- Identities - Exploration
of identities and connections among tensor and matrix
operations
- Importing and Exporting Tensor
Data - Covers
`import_data` and `export_data`
for reading and writing `tensor`, `sptensor`, and
`ktensor` objects
