Need to convert data from two sensors to the same sampling rate

Hi!
I have recorded data from two sensors with different sampling rates. I would like to convert both data vectors to the same sampling rate while preserving timing information of my waveforms. I have already researched using the resample command from the signal processing toolbox but I haven not been able to make it work for me.
Thank you!

Another suggestion, which is what I normally use for this type of problem: create a timeseries object and use the resample method.
HTH,

Use rat to get the upsample downsample ratio for the resample method. You shouldn't have issues with preserving timing information as resample compensates for the filters delay.

Perhaps interp1 to interpolate to the sampling rate you desire.

If you have Filter Design Toolbox or DSP System Toolbox, you may want to take a look at the documentation for fdesign.rsrc, it is specifically for rational rate conversion. There is also a demo named "Efficient Sample Rate Conversion between Arbitrary Factors" in the product.
