## Detailed Description

SOLVER API.

getrsBatched solves a batch of systems of n linear equations on n variables in its factorized forms.

For each instance i in the batch, it solves one of the following systems, depending on the value of trans:

$\begin{array}{cl} A_i X_i = B_i & \: \text{not transposed,}\newline A_i^T X_i = B_i & \: \text{transposed, or}\newline A_i^H X_i = B_i & \: \text{conjugate transposed.} \end{array}$

Matrix $$A_i$$ is defined by its triangular factors as returned by hipblasSgetrfBatched "getrfBatched".

Parameters
 [in] handle hipblasHandle_t. [in] trans hipblasOperation_t. Specifies the form of the system of equations of each instance in the batch. [in] n int. n >= 0. The order of the system, i.e. the number of columns and rows of all A_i matrices. [in] nrhs int. nrhs >= 0. The number of right hand sides, i.e., the number of columns of all the matrices B_i. [in] A Array of pointers to type. Each pointer points to an array on the GPU of dimension lda*n. The factors L_i and U_i of the factorization A_i = P_i*L_i*U_i returned by hipblasSgetrfBatched "getrfBatched". [in] lda int. lda >= n. The leading dimension of matrices A_i. [in] ipiv pointer to int. Array on the GPU. Contains the vectors ipiv_i of pivot indices returned by hipblasSgetrfBatched "getrfBatched". [in,out] B Array of pointers to type. Each pointer points to an array on the GPU of dimension ldb*nrhs. On entry, the right hand side matrices B_i. On exit, the solution matrix X_i of each system in the batch. [in] ldb int. ldb >= n. The leading dimension of matrices B_i. [out] info pointer to a int on the host. If info = 0, successful exit. If info = j < 0, the j-th argument is invalid. [in] batchCount int. batchCount >= 0. Number of instances (systems) in the batch.
