    )

This function computes the LU decomposition (without pivoting) of matrix \(A\)

\[\begin{equation*} {A = L U}\end{equation*}\]

where \(A\) is a dense matrix of size \(n \times n\) , \(L\) is a lower triangular matrix with unit diagonal, and \(U\) is an upper triangular matrix. This function does not implement pivoting.

The maximum matrix size supported in FPGA is templated by NMAX.

Parameters:

T data type (support float and double)
NMAX maximum number of rows/cols of input matrix
NCU number of computation unit
n number of rows/cols of matrix A
A input matrix
lda leading dimention of input matrix A
info output info (unused)
