Signature
def reconstruct_matrix_from_id ( B , idx , proj ) Summary
Reconstruct matrix from its ID.
Extended Summary
A matrix A with skeleton matrix B and ID indices and coefficients idx and proj, respectively, can be reconstructed as
numpy.hstack([B, numpy.dot(B, proj)])[:,numpy.argsort(idx)]See also reconstruct_interp_matrix and reconstruct_skel_matrix.
Parameters
B: :class:`numpy.ndarray`Skeleton matrix.
idx: :class:`numpy.ndarray`Column index array.
proj: :class:`numpy.ndarray`Interpolation coefficients.
Returns
: :class:`numpy.ndarray`Reconstructed matrix.
