In the DECIMATE's help ( http://www.mathworks.es/es/help/signal/ref/decimate.html ) says that:
-------------------------------------------------------------
Note: For better results when r is greater than 13, you should break r into its factors and call decimate several times.
-------------------------------------------------------------
I prefer to use RESAMPLE because I think it's better than DECIMATE. But in RESAMPLE's help
( http://www.mathworks.es/es/help/signal/ref/resample.html ) says nothing about if decimation factor must be less than 13 for better results.
So, can I use decimation factor with RESAMPLE greater than 13 and get good results?
Thank you,
José Manuel

resample uses upfirdn() under the hood, which is ultimately a MEX file implementation of a polyphase filtering of the input, so I believe you will find resample more efficient for larger factors.
