Detailed Description

Function for finding the sum of all elements in the input vector in specified parts.

Note

D - all protection domains

Supported types - bool / uint8 / uint16 / uint32 / uint / int8 / int16 / int32 / int / float32 / float64

Uses accumulator to calculate sum. May be very inefficient for private domains.

Parameters

vec	- input
k	- an uint type scalar which specifies in how many parts the sum is found. For example if k = 2 then the input vector is split into two parts and the sums of those parts are found seperately.

Returns

returns a vector with the sum of the specified number of parts in the input vector

Leakage

None
