Description

This function searches for

dstLen

maximum values and their indexes in an input vector. The function is designed to process large input vectors by small blocks, it takes into account results of previous blocks processing getting maximum values of

pSrc

and

pDstValue

and then combining the final results into

pDstValue

.

The

srcIndex

parameter stores the index of the first element

pSrc[0]

of each new block, thus supporting the continuous numbering of elements. Before calling the

ippsTopK

function, compute the required buffer size and initialize

pDstValue

and

pDstIndex

using the

ippsTopKGetBufferSize

and

ippsTopKInit_32s

functions, respectively.
