Hi y'all. I have two series of data, taken over a period of time and I want to know whether one set of data contains a signal similar to that in the other. I believe the way to do this is to use cross-correlation(*) and I notice that dir(pylab) now contains a function called cross_correlate, but given two arrays, that function returns a single scalar value (whereas I was expecting a list of correlation coefficients corresponding to how well the two signals match on successive lags).
So ... does matplotlib have something akin to what I'm after or is there an extention that might have it? Very many thanks, Sarah (*) http://www.mathworks.com/access/helpdesk/help/toolbox/garch/index.html?/access/helpdesk/help/toolbox/garch/crosscorr.html http://www.mathworks.com/access/helpdesk/help/toolbox/signal/index.html?/access/helpdesk/help/toolbox/signal/xcorr.html -- Work: http://www.cogentcomputing.org Blog: http://varspool.blogspot.com Photos: http://flickr.com/photos/sarahmount/ ------------------------------------------------------------------------- Using Tomcat but need to do more?
