Detailed Description

Function for obliviously looking up a column in a matrix.

Note

D - all protection domains

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

Parameters

mat	- a 2-dimensional matrix of supported type
colIndex	- an uint type scalar for specifying the column of the input matrix to look up

Returns

returns the column from the input matrix specified by colIndex

Leakage

None
