from_svd()

classmethod PODBasis.from_svd(leftvecs: ndarray, svdvals: ndarray, rightvecs: ndarray = None, num_vectors: int = None, svdval_threshold: float = None, residual_energy: float = None, cumulative_energy: float = None, projection_error: float = None, max_vectors: int = None, weights: ndarray = None, name: str = None)

Initialize a PODBasis from the singular value decomposition of an \(n\times k\) matrix.

Parameters

leftvecs(n, r) ndarray

Left singular vectors.

svdvals(r,) ndarray

Singular values.

rightvecs(k, r) ndarray or None

Right singular vectors. Each column is a singular vector.

Returns

Initialized PODBasis object.

Notes
