Detailed Description

BLAS Level 2 API.

The syr2StridedBatched functions perform the matrix-vector operations:

A[i] := A[i] + alpha*x[i]*y[i]**T + alpha*y[i]*x[i]**T

where alpha is a scalar, x[i] and y[i] are vectors, and A[i] is an n by n symmetric matrices, for i = 1 , ... , batchCount.

  • 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] specifies either upper (HIPBLAS_FILL_MODE_UPPER) or lower (HIPBLAS_FILL_MODE_LOWER):
  • If HIPBLAS_FILL_MODE_UPPER, the lower part of A is not referenced.
  • If HIPBLAS_FILL_MODE_LOWER, the upper part of A is not referenced.
[in]n- [int] the number of rows and columns of each matrix A.
[in]alphadevice pointer or host pointer to scalar alpha.
[in]x- device pointer to the first vector x_1.
[in]incx- [int] specifies the increment for the elements of each x_i.
[in]stridex- [hipblasStride] specifies the pointer increment between vectors (x_i) and (x_i+1).
[in]y- device pointer to the first vector y_1.
[in]incy- [int] specifies the increment for the elements of each y_i.
[in]stridey- [hipblasStride] specifies the pointer increment between vectors (y_i) and (y_i+1).
[in,out]AP- device pointer to the first matrix A_1.
[in]lda- [int] specifies the leading dimension of each A_i.
[in]strideA- [hipblasStride] stride from the start of one matrix (A_i) to the next one (A_i+1).
[in]batchCount- [int] number of instances in the batch.
