Detailed Description

Function for selecting k rows from a matrix ordered by a column.

Note

D - all protection domains

Supported types - uint8 / uint16 / uint32 / uint / int8 / int16 / int32 / int / xor_uint8 / xor_uint16 / xor_uint32 / xor_uint64

The number of rows of the input matrix has to be a power of two.

The algorithm behind this function is optimized for speed, accuracy is not guaranteed.

Parameters

matrix	- a matrix of supported type
k	- number of elements to select
column	- column to select by

Returns

returns a matrix with k rows selected from the input vector according to the input column index
