| integer(kind(rocblas_status_success)) function | rocblas_sgemmt_ (handle, uplo, transa, transb, n, k, alpha, a, lda, b, ldb, beta, c, ldc) |
Detailed Description
BLAS Level 3 API.
The gemmt functions perform matrix-matrix operations and update the upper or lower triangular part of the result matrix:
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, A and B are general matrices, and C is either an upper or lower triangular matrix, with op( A ) an n by k matrix, op( B ) a k by n matrix, and C an n by n matrix.
- Parameters
-
[in] handle - [rocblas_handle] handle to the rocBLAS library context queue. [in] uplo - [rocblas_fill] - rocblas_fill_upper: C is an upper triangular matrix.
- rocblas_fill_lower: C is a lower triangular matrix.
[in] transA - [rocblas_operation] - rocblas_operation_none: op(A) = A.
- rocblas_operation_transpose: op(A) = A^T
- rocblas_operation_conjugate_transpose: op(A) = A^H
[in] transB - [rocblas_operation] - rocblas_operation_none: op(B) = B.
- rocblas_operation_transpose: op(B) = B^T
- rocblas_operation_conjugate_transpose: op(B) = B^H
[in] n - [rocblas_int] number or rows of matrices op( A ), columns of op( B ), and (rows, columns) of C. [in] k - [rocblas_int] number of rows of matrices op( B ) and columns of op( A ). [in] alpha - device pointer or host pointer specifying the scalar alpha. [in] A - device pointer storing matrix A. If transa = rocblas_operation_none, then the leading n-by-k part of the array contains the matrix A. Otherwise, the leading k-by-n part of the array contains the matrix A. [in] lda - [rocblas_int] specifies the leading dimension of A. If transA == rocblas_operation_none, must have lda >= max(1, n). Otherwise, must have lda >= max(1, k). [in] B - device pointer storing matrix B. If transB = rocblas_operation_none, then the leading k-by-n part of the array contains the matrix B. Otherwise, the leading n-by-k part of the array contains the matrix B. [in] ldb - [rocblas_int] specifies the leading dimension of B. If transB == rocblas_operation_none, must have ldb >= max(1, k). Otherwise, must have ldb >= max(1, n). [in] beta - device pointer or host pointer specifying the scalar beta. [in,out] C - device pointer storing matrix C on the GPU. If uplo == rocblas_fill_upper, the upper triangular part of the leading n-by-n array contains the matrix C. Otherwise, the lower triangular part of the leading n-by-n array contains the matrix C. [in] ldc - [rocblas_int] specifies the leading dimension of C. Must have ldc >= max(1, n).
