Detailed Description
The POTRS functions solve a symmetric/Hermitian system of n linear equations on n variables in its factorized form.
It solves the system
\[ A X = B \]
where A is a real symmetric (complex Hermitian) positive definite matrix defined by its triangular factor
\[ \begin{array}{cl} A = U^H U & \: \text{if uplo is upper, or}\\% A = L L^H & \: \text{if uplo is lower.} \end{array} \]
as returned by POTRF.
- Parameters
-
[in] handle - rocblas_handle. [in] uplo - rocblas_fill. Specifies whether the factorization is upper or lower triangular. If uplo indicates lower (or upper), then the upper (or lower) part of A is not used. [in] n - rocblas_int. n >= 0. The order of the system, that is, the number of columns and rows of A. [in] nrhs - rocblas_int. nrhs >= 0. The number of right hand sides, that is, the number of columns of the matrix B. [in] A - pointer to type. Array on the GPU of dimension lda*n. The factor L or U of the Cholesky factorization of A returned by POTRF. [in] lda - rocblas_int. lda >= n. The leading dimension of A. [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.
