Detailed Description
!
SYGST_BATCHED reduces a batch of real symmetric-definite generalized eigenproblems to standard form.
(This is the blocked version of the algorithm).
For each instance in the batch, the problem solved by this function is either of the form \end{array} \f]
depending on the value of itype.
If the problem is of the 1st form, then \(A_i\) is overwritten with \end{array} \f]
where the symmetric-definite matrix \(B_i\) has been factorized as either \(U_i^T U_i\) or \(L_i L_i^T\) as returned by POTRF, depending on the value of uplo.
If the problem is of the 2nd or 3rd form, then A is overwritten with \end{array} \f]
also depending on the value of uplo.
- Parameters
-
[in] handle rocblas_handle. [in] itype #rocblas_eform.
Specifies the form of the generalized eigenproblems.[in] uplo rocblas_fill.
Specifies whether the upper or lower part of the matrices A_i are stored, and whether the factorization applied to B_i was upper or lower triangular. If uplo indicates lower (or upper), then the upper (or lower) parts of A_i and B_i are not used.[in] n rocblas_int. n >= 0.
The matrix dimensions.[in,out] A array of pointers to type. Each pointer points to an array on the GPU of dimension ldan.
On entry, the matrices A_i. On exit, the transformed matrices associated with the equivalent standard eigenvalue problems.[in] lda rocblas_int. lda >= n.
Specifies the leading dimension of A_i.[out] B array of pointers to type. Each pointer points to an array on the GPU of dimension ldbn.
The triangular factors of the matrices B_i, as returned by POTRF_BATCHED.[in] ldb rocblas_int. ldb >= n.
Specifies the leading dimension of B_i.[in] batch_count rocblas_int. batch_count >= 0.
Number of matrices in the batch.
