Autocorrelation functions, was Re: [PD-dev] using SIMD instructions in externals

[Ed Kelly]

Thanks again. The reason I am looking at this is because I'm doing a lot of work with autocorrelation functions and would really like to find ways of speeding them up. I'm using nested for loops, but maybe some form of matrix math is more appropriate. I've never studied maths in so much depth, but if anyone can point me to a way of making fast realtime versions of ACFs I would be extremely grateful! (and we will have a new external).
 
 Best,
 Ed
