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.
