Function rs_code_matrix 

Source 
pub fn rs_code_matrix<F: TwoAdicField + Ord>(
    l_skip: usize,
    log_blowup: usize,
    eval_matrix: &ColMajorMatrix<F>,
) -> Result<ColMajorMatrix<F>, StackedPcsError>
Expand description

Computes the Reed-Solomon codeword of each column vector of eval_matrix where the rate is 2^{-log_blowup}. The column vectors are treated as evaluations of a prismalinear extension on a hyperprism.
