- scipy.linalg.interpolative.reconstruct_interp_matrix(idx, proj)[source]#
- Reconstruct interpolation matrix from ID. - 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 - Bvia- A = B @ P- See also - reconstruct_matrix_from_idand- reconstruct_skel_matrix.- Parameters:
- idxnumpy.ndarray
- 1D column index array. 
- projnumpy.ndarray
- Interpolation coefficients. 
 
- idx
- Returns:
- numpy.ndarray
- Interpolation matrix.
