Detailed Description

BLAS Level 3 API.

gemm performs 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.

Parameters
[in]handle[rocblas_handle] handle to the rocblas library context queue.
[in]transA[rocblas_operation] specifies the form of op( A )
[in]transB[rocblas_operation] specifies the form of op( B )
[in]m[rocblas_int] number or rows of matrices op( A ) and C
[in]n[rocblas_int] number of columns of matrices op( B ) and C
[in]k[rocblas_int] number of columns of matrix op( A ) and number of rows of matrix op( B )
[in]alphadevice pointer or host pointer specifying the scalar alpha.
[in]Adevice pointer storing matrix A.
[in]lda[rocblas_int] specifies the leading dimension of A.
[in]Bdevice pointer storing matrix B.
[in]ldb[rocblas_int] specifies the leading dimension of B.
[in]betadevice pointer or host pointer specifying the scalar beta.
[in,out]Cdevice pointer storing matrix C on the GPU.
[in]ldc[rocblas_int] specifies the leading dimension of C.
