ah rotation matrix! good

oh grand! sorry, but i don't quite follow what "rotate the axis" means mathematically. a small example, somebody?

TMM, thanks for participation. Now, the only way to find modulus which i spotted is following: function F can be substituted by an integer number, which is its result. Therefore the F function is equal to simply (integer mod M) and the result will be numbers from 0 to M-1, like if M is 13, we...
