Hello,
I am looking for a low pass filter with a cutoff of 100Hz that will work in Octave. I have used the butter function, but I'm not sure I am using it properly becuase my outcome does not filter nicely. Any tips or samples would be greatly appreciated.
Thank you.

i never used octave yet, but you can have a look into a very easy low pass: the moving average filter. depending on the number of times you apply it and on the length of the filter you can achieve many different frequency responses. there are mutiple pages with that topic, you can googel it, i give you one example:
