Detailed Description

Function for obliviously choosing pointwise from the inputs.

Note

D - all protection domains

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

Parameters

cond	- a boolean array
first	- values for true case
second	- values for false case

Returns

pointwise check if cond at a certain position is true or false. if true the element of first at that position is returned else the element of second at that position is returned

Leakage

None
