Detailed Description

POTRS solves 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

\[ \begin{array}{cl} A = U'U & \: \text{if uplo is upper, or}\newline A = LL' & \: \text{if uplo is lower.} \end{array} \]

as returned by POTRF.

Parameters
[in]handlerocblas_handle.
[in]uplorocblas_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]nrocblas_int. n >= 0.
The order of the system, i.e. the number of columns and rows of A.
[in]nrhsrocblas_int. nrhs >= 0.
The number of right hand sides, i.e., the number of columns of the matrix B.
[in]Apointer 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]ldarocblas_int. lda >= n.
The leading dimension of A.
[in,out]Bpointer 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]ldbrocblas_int. ldb >= n.
The leading dimension of B.
