2.3.5 VectorDotProduct

Description

VectorDotProduct computes the sum of the products between the corresponding elements of the source one and source two vectors.

Prototype

fractional VectorDotProduct (int numElems, fractional* srcV1, fractional* srcV2);

Arguments


Parameters	Description
numElems	Number of elements in the source vectors
srcV1	Pointer to the source one vector
srcV2	Pointer to the source two vector

Returns

Value of the sum of products.

Remarks

If the absolute value of sum-of-products is larger than the maximum value of 1.31 fractional data type, the operation results in saturation.

This function can be computed in place.

This function can be self-applicable.
