How to use a matched filter to find a single in an array of data?

Hello,

I would like to use a matched filter to find a signal in an array of data and report back the indices of the signal. I have a pretty accurate template of the data. I know that this is a pretty trivial thing to do, but I haven't quite found what I need online. Maybe I'm looking in the wrong places?

thanks, windell

Alternatively, you can also use xcorr to achieve the same. Just find the indices for the peaks. You can find relevant examples here https://www.mathworks.com/help/signal/examples/measuring-signal-similarities.html
