spd_learn.functional.transport_euclid(X, A=None, B=None)[source]#

Parallel transport for Euclidean metric.

Parameters:

X (ndarray, shape (..., n, m)) – Matrices.
A (None | ndarray, shape (n, m), default=None) – Initial matrix, unused.
B (None | ndarray, shape (n, m), default=None) – Final matrix, unused.

Returns:

X_new – Matrices, equal to X.

Return type:

ndarray, shape (…, n, m)

Notes

Added in version 0.10.

Changed in version 0.12: Add support for NumPy and PyTorch.
