How to scale a dataset to fit an other dataset?

16 ビュー (過去 30 日間)
I am working on a filter for a heartbeat sensor. Therefore I want to fit a 'perfect' heart beat graph (without noise) onto a signal with noise. Is there a function in matlab to scale the 'perfect' data such that it fits onto the signal with noise?
Since a heart rate is not constant, the perfect graph needs to be scaled in both amplitude and time/frequency in order to fit it onto the signal with noise.

I recently found about Savitzky-Golay filter, which I think you will like it very much for your application.
Have a look at MATLAB help for
doc sgolay
Hope this helps.

Dear Roelst,
I'm glad that it helped.
If you have curve fitting toolbox, you may wanna have a loot at the fitting options, type cftool in command window and you will see the GUI
As far as I remember there are built in sin wave fittings, using multiple sins, you can even define your own custom function if you like.
Have a look at that, it may help you with the fitting.
