Cholesky Decomposition for SPD matrix (POTRF)

This function computes the Cholesky decomposition of matrix \(A\)

\[A = L {L}^T\]

where \(A\) is a dense symmetric positive-definite matrix of size \(m \times m\), \(L\) is a lower triangular matrix, and \({L}^T\) is the transposed matrix of \(L\). The maximum matrix size supported in FPGA is templated by NMAX.
