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.
