## Detailed Description

GESV solves a general system of n linear equations on n variables.

The linear system is of the form

$A X = B$

where A is a general n-by-n matrix. Matrix A is first factorized in triangular factors L and U using GETRF; then, the solution is computed with GETRS.

Parameters
 [in] handle rocblas_handle. [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. On entry, the matrix A. On exit, if info = 0, the factors L and U of the LU decomposition of A returned by GETRF. [in] lda rocblas_int. lda >= n. The leading dimension of A. [out] 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. [out] info pointer to a rocblas_int on the GPU. If info = 0, successful exit. If info = i > 0, U is singular, and the solution could not be computed. U[i,i] is the first zero element in the diagonal.
