Convert ID to SVD.
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 : numpy.ndarray
idx : numpy.ndarray
proj : numpy.ndarray
|
---|---|
Returns: | U : numpy.ndarray
S : numpy.ndarray
V : numpy.ndarray
