MtxVec VCL
|
Scalar product of two real arrays.
Calculates the dot product (scalar value) of the calling object and Vec object and returns a real scalar value. The result is stored at specified index in the calling vector in the GPU memory. This variant of the function is non-blocking (faster), because the result does not have to be copied to the CPU memory to be used.
The dot product is defined by the equation:
Both objects must be of equal size. If they are not, the method will return the dot product of the largest sub-array.
