integer(kind(hipblas_status_success)) function	hipblashgemm_ (handle, transa, transb, m, n, k, alpha, ap, lda, bp, ldb, beta, cp, ldc)

Detailed Description

BLAS Level 3 API.

The gemm functions perform one of the matrix-matrix operations:

C = alpha*op( A )*op( B ) + beta*C,

where op( X ) is one of:

op( X ) = X      or
op( X ) = X**T   or
op( X ) = X**H,

alpha and beta are scalars, and A, B, and C are matrices, with op( A ) an m by k matrix, op( B ) a k by n matrix, and C an m by n matrix.

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

Parameters

[in]	handle	- [hipblasHandle_t] handle to the hipBLAS library context queue.
[in]	transA	- [hipblasOperation_t] specifies the form of op( A ).
[in]	transB	- [hipblasOperation_t] specifies the form of op( B ).
[in]	m	- [int] number or rows of matrices op( A ) and C.
[in]	n	- [int] number of columns of matrices op( B ) and C.
[in]	k	- [int] number of columns of matrix op( A ) and number of rows of matrix op( B ).
[in]	alpha	- device pointer or host pointer specifying the scalar alpha.
[in]	AP	- device pointer storing matrix A.
[in]	lda	- [int] specifies the leading dimension of A.
[in]	BP	- device pointer storing matrix B.
[in]	ldb	- [int] specifies the leading dimension of B.
[in]	beta	- device pointer or host pointer specifying the scalar beta.
[in,out]	CP	- device pointer storing matrix C on the GPU.
[in]	ldc	- [int] specifies the leading dimension of C.
