I recently got the following error:

The input signal X must be a double-precision vector.

Now, I understand the error and how to fix it, so I just left myself a note to make sure the data I load uses double precision instead of single. However, now that I'm trying to actually implement the fix, I can't recreate the error! Is there a list of functions which will give this error if not provided a double-precision vector?

You can search for this string in the toolbox functions. I use the free GrepWin under Windows.

In some Matlab versions filter did not support single input.

Thanks for the tip on searching the code! I just used the native search in Explorer to get the list. The function that was causing the issue for me was `findpeaks`.
