scipy.linalg.interpolative.id_to_svd#
- scipy.linalg.interpolative.id_to_svd(B, idx, proj)[source]#
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))
