Function random_binary_matrix 

pub fn random_binary_matrix(
    n_rows: usize,
    n_cols: usize,
    density: f64,
    seed: Option<u64>,
) -> StatsResult<Array2<i32>>

Generate a random binary matrix with specified shape and density

Arguments

• n_rows - Number of rows
• n_cols - Number of columns
• density - Probability of non-zero elements
• seed - Optional seed for reproducibility

Returns

• Random binary matrix

Examples

use scirs2_stats::random::random_binary_matrix;

// Generate a 5x5 binary matrix with 30% non-zero elements
let matrix = random_binary_matrix(5, 5, 0.3, Some(42)).expect("Operation failed");

// The matrix should have the correct shape
assert_eq!(matrix.shape(), &[5, 5]);

// All elements should be either 0 or 1
for &val in matrix.iter() {
    assert!(val == 0 || val == 1);
}
