Logical Indexing with matrix

Helllo,

Assuming I have three matrices:

A = [1 0 ; 0 1]
B = [1 1 ; 1 1]
C = [3 4 ; 6 7]

I would like to perform the following operation

C = C ( A & B ) +1 

That is: adding 1 to the elements of the matrix C that meet the condition, but it's not working.

Any ideaa of how to do it ?

C( A & B ) = C( A & B ) + 1

Sure, It was trivial..
