Detailed Description

SOLVER API.

getriBatched computes the inverse \(C_i = A_i^{-1}\) of a batch of general n-by-n matrices \(A_i\).

The inverse is computed by solving the linear system

\[ A_i C_i = I \]

where I is the identity matrix, and \(A_i\) is factorized as \(A_i = P_i L_i U_i\) as given by hipblasSgetrfBatched "getrfBatched".

Parameters

[in]	handle	hipblasHandle_t.
[in]	n	int. n >= 0. The number of rows and columns of all matrices A_i in the batch.
[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. Specifies the leading dimension of matrices A_i.
[in]	ipiv	pointer to int. Array on the GPU (the size depends on the value of strideP). The pivot indices returned by hipblasSgetrfBatched "getrfBatched". ipiv can be passed in as a nullptr, this will assume that getrfBatched was called without partial pivoting.
[out]	C	array of pointers to type. Each pointer points to an array on the GPU of dimension ldc*n. If info[i] = 0, the inverse of matrices A_i. Otherwise, undefined.
[in]	ldc	int. ldc >= n. Specifies the leading dimension of C_i.
[out]	info	pointer to int. Array of batchCount integers on the GPU. If info[i] = 0, successful exit for inversion of A_i. If info[i] = j > 0, U_i is singular. U_i[j,j] is the first zero pivot.
[in]	batchCount	int. batchCount >= 0. Number of matrices in the batch.
