### Sine or Cosine of every element in Mat (c++)

I was wondering if there is any way to take the sine or cosine of every element in a matrix?

Thanks!

I was wondering if there is any way to take the sine or cosine of every element in a matrix?

Thanks!

EDIT: For future reference, I did the Taylor expansion of Sine. For pretty good accuracy, I only had calculate up to the fourth term. However, keep note that if you are trying to estimate sin(pi) or sin(-pi) you have to calculate additional terms (probably 8 total terms).
