pub fn nuclear_norm<F>(
a: &ArrayView2<'_, F>,
workers: Option<usize>,
) -> LinalgResult<F>
Expand description
Compute the nuclear norm (trace norm) of a matrix.
The nuclear norm is the sum of singular values, which for symmetric matrices is the sum of absolute eigenvalues.
§Arguments
a
- Input matrixworkers
- Number of worker threads (None = use default)
§Returns
- Nuclear norm of the matrix
§Examples
use scirs2_core::ndarray::array;
use scirs2_linalg::matrix_functions::nuclear_norm;
let a = array![[2.0_f64, 0.0], [0.0, 3.0]];
let norm = nuclear_norm(&a.view(), None).unwrap();
// norm should be 5.0
