scipy.linalg.interpolative:id_to_svd
Signature
def id_to_svd ( B , idx , proj ) Summary
Convert ID to SVD.
Extended Summary
The SVD reconstruction of a matrix with skeleton matrix B and ID indices and coefficients idx and proj, respectively, is
U, S, V = id_to_svd(B, idx, proj) A = numpy.dot(U, numpy.dot(numpy.diag(S), V.conj().T))
See also svd.
Parameters
B: :class:`numpy.ndarray`Skeleton matrix.
idx: :class:`numpy.ndarray`1D column index array.
proj: :class:`numpy.ndarray`Interpolation coefficients.
Returns
U: :class:`numpy.ndarray`Left singular vectors.
S: :class:`numpy.ndarray`Singular values.
V: :class:`numpy.ndarray`Right singular vectors.
