integer(kind(hipblas_status_success)) function hipblasstrsvbatched_ (handle, uplo, transa, diag, n, ap, lda, x, incx, batchcount)
 

Detailed Description

BLAS Level 2 API.

The trsvBatched functions solve: 

 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 n by n triangular matrix.

The vector x is overwritten on b.

  • Supported precisions in rocBLAS : s, d, c, and z.
  • Supported precisions in cuBLAS : No support.
Parameters
[in]handle- [hipblasHandle_t] handle to the hipBLAS library context queue.
[in]uplo- [hipblasFillMode_t]
  • HIPBLAS_FILL_MODE_UPPER: A is an upper triangular matrix.
  • HIPBLAS_FILL_MODE_LOWER: A is a lower triangular matrix.
[in]transA- [hipblasOperation_t]
[in]diag- [hipblasDiagType_t]
  • HIPBLAS_DIAG_UNIT: A is assumed to be unit triangular.
  • HIPBLAS_DIAG_NON_UNIT: A is not assumed to be unit triangular.
[in]n- [int] n specifies the number of rows of b. n >= 0.
[in]AP- device array of device pointers storing each matrix A_i.
[in]lda- [int] specifies the leading dimension of each A_i. lda = max(1, n).
[in]x- device array of device pointers storing each vector x_i.
[in]incx- [int] specifies the increment for the elements of x.
[in]batchCount- [int] number of instances in the batch
