Detailed Description

Function for obliviously updating a value 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
rowIndex	- an uint type scalar for specifying the row in the input matrix
colIndex	- an uint type scalar for specifying the column in the input matrix
newValue	- a new scalar value

Returns

returns a matrix where the element at row rowIndex and column colIndex has been replaced with newValue

Leakage

None
