WebNov 25, 2024 · Since you are making a periodic function, the mod(x,2) simply puts all of the input values into the range of one cycle. From there it is just a matter of forming the proper outputs of one cycle. The y=x part for the [0,1] input didn't need any adjustment so no extra code for that. Only the [1,2] part needed the extra code. WebThis commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
