title: Using the iOS Accelerate Framework for Data Smoothing
body: <p>Does anyone have any pointers to using the Accelerate Framework for Data Smoothing...? I am looking to smooth data based on inputs to the accelerometers. I currently do some basic filtering of incoming accelerometer data points and then pass the data to a function that then performs some calculations based on this. I then would like to do some further data smoothing on the processed data.</p>
  
  <p>I currently have a prototype that uses a Python library that performs a Savitzky-Golay filter on the resulting data. I then use the output from that in my App. My prototype calculates data nicely, however I want to do this in either Objective-C / Swift. I would also like to use the Accelerate Framework for performance reasons. So far I haven't seen any pointers to how I could use the Accelerate Framework for data smoothing, hence my question.</p>
  
  <p>If any one has any pointers or documentation, then please let me know.</p>
  
  <p>Thanks,</p>
