StrictLowerTriQSM

class tinygp.solvers.quasisep.core.StrictLowerTriQSM(p: JAXArray, q: JAXArray, a: JAXArray)

Bases: QSM

A strictly lower triangular order m quasiseparable matrix

Parameters:

• p (n, m) – The left quasiseparable elements.

• q (n, m) – The right quasiseparable elements.

• a (n, m, m) – The transition matrices.

scale(other: tinygp.helpers.JAXArray) → StrictLowerTriQSM

The multiplication of this matrix times a scalar, as a QSM

self_add(other: StrictLowerTriQSM) → StrictLowerTriQSM

The sum of two StrictLowerTriQSM matrices

self_mul(other: StrictLowerTriQSM) → StrictLowerTriQSM

The elementwise product of two StrictLowerTriQSM matrices

property shape: tuple[int, int]

The shape of the matrix

to_dense() → tinygp.helpers.JAXArray

Render this representation to a dense matrix

This implementation is not optimized and should really only ever be used for testing purposes.

transpose() → StrictUpperTriQSM

The matrix transpose as a QSM
