Detailed Description

BLAS Level 2 API.

The syr functions perform the matrix-vector operations:

A := A + alpha*x*x**T

where alpha is a scalar, x is a vector, and A is an n by n symmetric matrix.

• Supported precisions in rocBLAS : s, d, c, and z.
• Supported precisions in cuBLAS : s, d, c, and z.

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 matrix A.
[in]	alpha	device pointer or host pointer to scalar alpha.
[in]	x	- device pointer storing vector x.
[in]	incx	- [int] specifies the increment for the elements of x.
[in,out]	AP	- device pointer storing matrix A.
[in]	lda	- [int] specifies the leading dimension of A.
