2.3.2 VectorConvolve

Description

VectorConvolve computes the convolution between two source vectors and stores the result in a destination vector. The result is computed as follows:

Where,

x[k] = source one vector of size N,

h[k] = source two vector of size M (with M < N).

Prototype

fractional* VectorConvolve (int numElems1,int numElems2,fractional* dstV, fractional* srcV1,fractional* srcV2);

Arguments


Parameters	Description
numElems1	Number of elements in source one vector
numElems2	Number of elements in source two vector
dstV	Pointer to the destination vector
srcV1	Pointer to the source one vector
srcV2	Pointer to the source two vector

Returns

Pointer to the base address of the destination vector.

Remarks

The number of elements in the source two vector must be less than or equal to the number of elements in the source one vector.

The destination vector must already exist, with exactly numElems1+numElems2-1 number of elements.

This function can be self-applicable.
