scipy.linalg.interpolative:reconstruct_interp_matrix
source: build-install/usr/lib/python3.14/site-packages/scipy/linalg/interpolative.py:573
Signature
def reconstruct_interp_matrix(idx, proj)Summary
Reconstruct interpolation matrix from ID.
Extended Summary
The interpolation matrix can be reconstructed from the ID indices and coefficients idx and proj, respectively, as
P = numpy.hstack([numpy.eye(proj.shape[0]), proj])[:,numpy.argsort(idx)]The original matrix can then be reconstructed from its skeleton matrix B via A = B @ P
See also reconstruct_matrix_from_id and reconstruct_skel_matrix.
Parameters
idx: :class:`numpy.ndarray`1D column index array.
proj: :class:`numpy.ndarray`Interpolation coefficients.
Returns
: :class:`numpy.ndarray`Interpolation matrix.
