Function gen_uniform_matrix 

pub fn gen_uniform_matrix(
    size: usize,
    rank: usize,
    modulus: i64,
    seed: Option<u64>,
) -> Vec<Vec<Polynomial<i64>>>

generates a rank x rank matrix of degree size-1 polynomials with uniform coefficients in Z_modulus

Arguments

• size - degree of the polynomials
• rank - rank of the matrix
• modulus - modulus
• seed - seed for the random number generator

Returns

• m - matrix of polynomials
