- 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)) - See also - svd.- Parameters:
- Bnumpy.ndarray
- Skeleton matrix. 
- idxnumpy.ndarray
- 1D column index array. 
- projnumpy.ndarray
- Interpolation coefficients. 
 
- B
- Returns:
- Unumpy.ndarray
- Left singular vectors. 
- Snumpy.ndarray
- Singular values. 
- Vnumpy.ndarray
- Right singular vectors. 
 
- U
