Struct MatrixLuciRowInterpolation 

pub struct MatrixLuciRowInterpolation<T> {
    pub rows: Vec<usize>,
    pub interpolation: Matrix<T>,
    pub pivot_magnitudes: Vec<f64>,
}

Row interpolation A ~= interpolation * A[rows, :] selected by MatrixLUCI. Unlike MatrixLuciFactors, this does not build an unused right factor.

Examples

use tensor4all_core::matrix_luci_row_interpolation_owned_in;
use tensor4all_tensorbackend::{default_cpu_execution_context, Matrix};
let a = Matrix::from_col_major_vec(2, 1, vec![2.0_f64, 4.0]);
let id = matrix_luci_row_interpolation_owned_in(a, None, &default_cpu_execution_context())?;
assert_eq!(id.rows, vec![1]);
assert_eq!(id.interpolation.as_col_major_slice(), &[0.5, 1.0]);

Fields

rows: Vec<usize>

Original matrix row indices, in pivot order.

interpolation: Matrix<T>

Row weights, with an identity submatrix at the selected rows.

pivot_magnitudes: Vec<f64>

Accepted LU pivot magnitudes followed by the maximum absolute entry of the remaining Schur complement. This is a local matrix diagnostic.
