Function rrlu 

pub fn rrlu<T: Scalar>(
    a: &Matrix<T>,
    options: Option<RrLUOptions>,
) -> Result<RrLU<T>>

Perform rank-revealing LU decomposition (non-destructive).

Clones the input matrix and calls rrlu_inplace.

Errors

Returns MatrixCIError::NaNEncountered if NaN values appear in the L or U factors.

Examples

use tensor4all_tcicore::{from_vec2d, matrixlu::rrlu};

let m = from_vec2d(vec![
    vec![1.0_f64, 0.0],
    vec![0.0, 2.0],
]);
let lu = rrlu(&m, None).unwrap();
assert_eq!(lu.npivots(), 2);
assert_eq!(lu.nrows(), 2);
assert_eq!(lu.ncols(), 2);
