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

Detailed Description

BLAS Level 2 API.

The tpsvBatched functions solve: 

 A_i*x_i = b_i or A_i**T*x_i = b_i, or A_i**H*x_i = b_i,

where x_i and b_i are vectors and A_i is a triangular matrix stored in the packed format, for i in [1, batchCount].

The input vectors b_i are overwritten by the output vectors x_i.

  • 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: each A_i is an upper triangular matrix.
  • HIPBLAS_FILL_MODE_LOWER: each A_i is a lower triangular matrix.
[in]transA- [hipblasOperation_t]
  • HIPBLAS_OP_N: Solves A*x = b
  • HIPBLAS_OP_T: Solves A**T*x = b
  • HIPBLAS_OP_C: Solves A**H*x = b
[in]diag- [hipblasDiagType_t]
  • HIPBLAS_DIAG_UNIT: each A_i is assumed to be unit triangular (that is, the diagonal elements of each A_i are not used in computations).
  • HIPBLAS_DIAG_NON_UNIT: each A_i is not assumed to be unit triangular.
[in]n- [int] n specifies the number of rows of each b_i. n >= 0.
[in]AP- device array of device pointers storing the packed versions of each matrix A_i of dimension >= (n * (n + 1) / 2).
[in,out]x- device array of device pointers storing each input vector b_i, overwritten by x_i on output.
[in]incx- [int] specifies the increment for the elements of each x_i.
[in]batchCount- [int] specifies the number of instances in the batch.
