Correlate Signals with different time points

I have two datasets (simulation and experimental) with normalised amplitudes, and I need to find a correlation coefficient for the two outputs. The problem is that these two signals have their values taken at different timesteps to each other, so how can I correlate them? Additionally how could I correlate them if the two datasets were at different lengths?

hello

is the delta in time steps constant or not ?

have you tried to use xcorr to measure (and correct) for delay ?

You can resample the data into sime sampling time:

doc resample
doc retime
doc interp1

After both signals are sampled in the same time grid:

doc crosscorr
doc xcorr
