Function isa_l::gf_gen_cauchy1_matrix

#[must_use]pub fn gf_gen_cauchy1_matrix(k: usize, m: usize) -> Vec<u8>

Generate a Cauchy matrix of coefficients to be used for encoding.

Cauchy matrix example of encoding coefficients where high portion of matrix is identity matrix I and lower portion is constructed as 1/(i + j) | i != j, i:{0,k-1} j:{k,m-1}. Any sub-matrix of a Cauchy matrix should be invertable.

Arguments:

• m: number of rows in matrix corresponding to srcs + parity.
• k: number of columns in matrix corresponding to srcs.
