Function random_sym_array

pub fn random_sym_array<T>(
    n: usize,
    density: f64,
    format: &str,
) -> SparseResult<Box<dyn SymSparseArray<T>>>
where
    T: Float + Debug + Copy + 'static + Add<Output = T> + Sub<Output = T> + Mul<Output = T> + Div<Output = T>,

Create a random symmetric sparse matrix with given density

Arguments

• n - Size of the matrix (n x n)
• density - Density of non-zero elements (0.0 to 1.0)
• format - Format of the output matrix (“csr” or “coo”)

Returns

A random symmetric sparse matrix

Examples

use scirs2_sparse::construct_sym::random_sym_array;

// Create a 10x10 symmetric random matrix with 20% density
let random = random_sym_array::<f64>(10, 0.2, "csr").unwrap();

assert_eq!(random.shape(), (10, 10));

// Check that it's symmetric
assert!(random.is_symmetric());

// The actual density may vary slightly due to randomness
