Detailed Description

BLAS Level 2 API.

her2 performs the matrix-vector operations

A := A + alpha*x*y**H + conj(alpha)*y*x**H

where alpha is a complex scalar, x and y are vectors, and A is an n by n Hermitian matrix.

Parameters
[in]handle[hipblasHandle_t] handle to the hipblas library context queue.
[in]uplo[hipblasFillMode_t] specifies whether the upper 'HIPBLAS_FILL_MODE_UPPER' or lower 'HIPBLAS_FILL_MODE_LOWER' HIPBLAS_FILL_MODE_UPPER: The upper triangular part of A is supplied. HIPBLAS_FILL_MODE_LOWER: The lower triangular part of A is supplied.
[in]n[int] the number of rows and columns of matrix A, must be at least 0.
[in]alphadevice pointer or host pointer to scalar alpha.
[in]xdevice pointer storing vector x.
[in]incx[int] specifies the increment for the elements of x.
[in]ydevice pointer storing vector y.
[in]incy[int] specifies the increment for the elements of y.
[in,out]Adevice pointer storing the specified triangular portion of the Hermitian matrix A. Of size (lda, n). if uplo == HIPBLAS_FILL_MODE_UPPER: The upper triangular portion of the Hermitian matrix A is supplied. The lower triangular portion of A will not be touched. if uplo == HIPBLAS_FILL_MODE_LOWER: The lower triangular portion of the Hermitian matrix A is supplied. The upper triangular portion of A will not be touched. Note that the imaginary part of the diagonal elements are not accessed and are assumed to be 0.
[in]lda[int] specifies the leading dimension of A. Must be at least max(lda, 1).
