Detailed Description
BLAS Level 2 API.
The syrStridedBatched functions perform the matrix-vector operations:
A[i] := A[i] + alpha*x[i]*x[i]**T
where alpha is a scalar, x is a pointer to an array of vectors, and A is an array of n by n symmetric matrices, for i = 1 , ... , batchCount.
- Supported precisions in rocBLAS :
s,d,c, andz. - 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] alpha device 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,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.
