Detailed Description

BLAS Level 3 API.

The syr2k functions perform one of the matrix-matrix operations for a symmetric rank-2k update:

C := alpha*(op( A )*op( B )^T + op( B )*op( A )^T) + beta*C

where alpha and beta are scalars, op(A) and op(B) are n by k matrices, and C is a symmetric n by n matrix stored as either upper or lower.

op( A ) = A, op( B ) = B, and A and B are n by k if trans == HIPBLAS_OP_N
op( A ) = A^T, op( B ) = B^T,  and A and B are k by n if trans == HIPBLAS_OP_T

• 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] HIPBLAS_FILL_MODE_UPPER: C is an upper triangular matrix. HIPBLAS_FILL_MODE_LOWER: C is a lower triangular matrix.
[in]	transA	- [hipblasOperation_t] HIPBLAS_OP_T: op( A ) = A^T, op( B ) = B^T HIPBLAS_OP_N: op( A ) = A, op( B ) = B
[in]	n	- [int] n specifies the number of rows and columns of C. n >= 0.
[in]	k	- [int] k specifies the number of columns of op(A) and op(B). k >= 0.
[in]	alpha	alpha specifies the scalar alpha. When alpha is zero, then A is not referenced and does not need to be set before entry.
[in]	AP	- Pointer storing matrix A on the GPU. Matrix dimension is ( lda, k ) when trans = HIPBLAS_OP_N. Otherwise, (lda, n). Only the upper/lower triangular part is accessed.
[in]	lda	- [int] lda specifies the first dimension of A. If trans = HIPBLAS_OP_N, lda >= max( 1, n ). Otherwise, lda >= max( 1, k ).
[in]	BP	- pointer storing matrix B on the GPU. Matrix dimension is ( ldb, k ) when trans = HIPBLAS_OP_N. Otherwise, (ldb, n). Only the upper/lower triangular part is accessed.
[in]	ldb	- [int] ldb specifies the first dimension of B. If trans = HIPBLAS_OP_N, ldb >= max( 1, n ). Otherwise, ldb >= max( 1, k ).
[in]	beta	beta specifies the scalar beta. When beta is zero, then C does not need to be set before entry.
[in]	CP	- pointer storing matrix C on the GPU.
[in]	ldc	- [int] ldc specifies the first dimension of C. ldc >= max( 1, n ).
