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.
