CuviStatus matMulTrans(const CuviImage& A,
CuviImage& B,
bool trans = false,
const CuviStream& stream = CuviStream()); |
Parameters
| Name | Type | Description |
|---|---|---|
| A | CuviImage& | Input Image |
| B | CuviImage& | Resultant Image |
| stream | CuviStream& | GPU stream ID for execution |
Image Type Support
| Input | Output |

| 32f single channel | 32f single channel |
Example
CuviSize aSize(3,3);
//Initialize input image
CuviImage A(aSize, CUVI_32FC1);
//Fill image with random values
cuvi::dataExchange::generateRandomImage(A);
CuviImage B;
//Perform matrix multiplication (A * A')
cuvi::arithmeticLogical::matMulTrans(A,B);
//The order of multiplication can be reversed to (A' * A)
cuvi::arithmeticLogical::matMulTrans(A,B,true); |
