Detailed Description
BLAS Level 2 API.
trsv_strided_batched solves
A_i*x_i = b_i or A_i**T*x_i = b_i,
where (A_i, x_i, b_i) is the i-th instance of the batch. x_i and b_i are vectors and A_i is an m by m triangular matrix, for i = 1, ..., batch_count.
The vector x is overwritten on b.
- Parameters
-
[in] handle [rocblas_handle] handle to the rocblas library context queue. [in] uplo [rocblas_fill] rocblas_fill_upper: A is an upper triangular matrix. rocblas_fill_lower: A is a lower triangular matrix. [in] transA [rocblas_operation] [in] diag [rocblas_diagonal] rocblas_diagonal_unit: A is assumed to be unit triangular. rocblas_diagonal_non_unit: A is not assumed to be unit triangular. [in] m [rocblas_int] m specifies the number of rows of each b_i. m >= 0. [in] A device pointer to the first matrix (A_1) in the batch, of dimension ( lda, m ) [in] stride_A [rocblas_stride] stride from the start of one A_i matrix to the next A_(i + 1) [in] lda [rocblas_int] specifies the leading dimension of each A_i. lda = max( 1, m ). [in,out] x device pointer to the first vector (x_1) in the batch. [in] stride_x [rocblas_stride] stride from the start of one x_i vector to the next x_(i + 1) [in] incx [rocblas_int] specifies the increment for the elements of each x_i. [in] batch_count [rocblas_int] number of instances in the batch
