decompress()

LinearBasis.decompress(states_compressed: ndarray, locs=None) → ndarray

Map low-dimensional latent coordinates to high-dimensional states.

\[\qhat \mapsto \breve{\q} = \Vr\qhat\]

Parameters:

states_compressed(r, …) ndarray

Matrix of r-dimensional latent coordinate vectors, or a single coordinate vector.

locsslice or (p,) ndarray of integers or None

If given, return the decompressed state at only the p specified locations (indices) described by locs.

Returns:

states_decompressed(n, …) or (p, …) ndarray

Matrix of n-dimensional decompressed state vectors, or the p entries of such at the entries specified by locs.
