Detailed Description

Function for obliviously updating a column in the input matrix.

Note

D - all protection domains

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

Parameters

mat	- a matrix of supported type
colIndex	- an uint type scalar for specifying the column to replace
newCol	- a vector with new values

Returns

returns a matrix where the column at colIndex has been replaced with newCol

Leakage

None
