Support pinv

13

We need `np.linalg.pinv`, in both the backends and on `Tensor`.

Add Cholesky decomposition

17

We should support the Cholesky decomposition per https://numpy.org/doc/stable/reference/generated/numpy.linalg.cholesky.html#numpy.linalg.cholesky, adding a pivot argument in the same way as qr and svd.

Add power to each backend and as a Tensor method in linalg

28

We should support the numpy function np.power. Edit: it would also be good to support elementwise exponentiation of `Tensor` using the `**` operator

Replace GMRES with a wrapper to the Jax version

5

Jax proper now supports GMRES, and the version there should be better than ours in several ways. If we are willing to enforce that one have the latest Jax version...

Add `item` for Tensor

6

Tensor should support the numpy-like function `item`, which converts a size-1 Tensor into a Python scalar.

Move towards consistent use of the term Tensor

2

Right now there's a bit of a confusing situation going on where the term `Tensor` refers both to the type of a given backend array (the old use) and to...
