I'm trying to implement an encryption technique using Matlab for a college project.
However I'm facing some difficulties in modular calculation.
For example I have matrix A = [ 1 , 0 ; 1/2 , 1 ] , and I need to calculate A mod 29.
what I'm getting in matlab is [ 1 , 0 ; 1/2 ,1 ],
Actually I don't understand the math behined the fact that (1/2 mod 29) = 15 .
So, if any one can help me in getting this result in Matlab, I would be grateful.
