template < typename T, int NMAX, int NCU > void trtrs ( char uplo, int m, T* A, int b, T* B, int lda, int ldb, int& info )
This function solves a system of linear equation with triangular coefficient matrix along with multiple right-hand side vector
\[\begin{equation*} {Ax=B}\end{equation*}\]
where \(A\) is a dense lower or upper triangular matrix of size \(m \times m\) , \(x\) is a vector need to be computed, and \(B\) is input vector.
The maximum matrix size supported in FPGA is templated by NMAX.
Parameters:
| T | data type (support float and double) |
| NMAX | maximum number of rows/columns of input matrix |
| NCU | number of computation unit |
| m | number of rows/cols of matrix A |
| A | input matrix of size \(n \times n\) |
| b | number of columns of matrix B |
| B | input matrix of size \(b \times n\) , and overwritten by the output matrix x |
| lda | leading dimention of input matrix A |
| ldb | leading dimention of input matrix B |
| info | output info (unused) |
