Detailed Description

GETRS solves a system of n linear equations on n variables in its factorized form.

It solves one of the following systems, depending on the value of trans:

\[ \begin{array}{cl} A X = B & \: \text{not transposed,}\newline A^T X = B & \: \text{transposed, or}\newline A^H X = B & \: \text{conjugate transposed.} \end{array} \]

Matrix A is defined by its triangular factors as returned by GETRF.

Parameters

[in]	handle	rocblas_handle.
[in]	trans	rocblas_operation. Specifies the form of the system of equations.
[in]	n	rocblas_int. n >= 0. The order of the system, i.e. the number of columns and rows of A.
[in]	nrhs	rocblas_int. nrhs >= 0. The number of right hand sides, i.e., the number of columns of the matrix B.
[in]	A	pointer to type. Array on the GPU of dimension lda*n. The factors L and U of the factorization A = P*L*U returned by GETRF.
[in]	lda	rocblas_int. lda >= n. The leading dimension of A.
[in]	ipiv	pointer to rocblas_int. Array on the GPU of dimension n. The pivot indices returned by GETRF.
[in,out]	B	pointer to type. Array on the GPU of dimension ldb*nrhs. On entry, the right hand side matrix B. On exit, the solution matrix X.
[in]	ldb	rocblas_int. ldb >= n. The leading dimension of B.
