Algorithm implemented in the timeseries\resample function of Matlab Does anyone know what algorithm is implemented in the Matlab function resample for timeseries?

I had a look on the manual but it just gives the instruction to use it: http://it.mathworks.com/help/matlab/ref/resampletscollection.html

Since the syntax is different from the one used for the usual resample (http://it.mathworks.com/help/ident/ref/resample.html) I assumed is not the same algorithm. Am I right?
See http://www.mathworks.com/help/matlab/ref/timeseries.setinterpmethod.html 
Seems to a choice between a few fairly simple interpolation schemes. The standard resample() uses a polyphase filter interpolation which is much better for most applications.
