Detailed Description

Function for obliviously looking up an element in the input 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
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

Returns

returns the element from the input matrix specified by rowIndex and colIndex

Leakage

None
