[−][src]Function opencv::cudaarithm::gemm

pub fn gemm(
    src1: &dyn ToInputArray, 
    src2: &dyn ToInputArray, 
    alpha: f64, 
    src3: &dyn ToInputArray, 
    beta: f64, 
    dst: &mut dyn ToOutputArray, 
    flags: i32, 
    stream: &mut Stream
) -> Result<()>

Performs generalized matrix multiplication.

Parameters

  • src1: First multiplied input matrix that should have CV_32FC1 , CV_64FC1 , CV_32FC2 , or CV_64FC2 type.
  • src2: Second multiplied input matrix of the same type as src1 .
  • alpha: Weight of the matrix product.
  • src3: Third optional delta matrix added to the matrix product. It should have the same type as src1 and src2 .
  • beta: Weight of src3 .
  • dst: Destination matrix. It has the proper size and the same type as input matrices.
  • flags: Operation flags:
  • GEMM_1_T transpose src1
  • GEMM_2_T transpose src2
  • GEMM_3_T transpose src3
  • stream: Stream for the asynchronous version.

The function performs generalized matrix multiplication similar to the gemm functions in BLAS level 3. For example, gemm(src1, src2, alpha, src3, beta, dst, GEMM_1_T + GEMM_3_T) corresponds to

block formula

Note: Transposition operation doesn't support CV_64FC2 input type.
