When I used filtfilt in version R2019b, I had to use input data in double format, but in version R2024, functions can recognize data in single format.But when I increased the order of the filter from second to third order, it became clear that the single format version produced the wrong result, and the result using the double version is still right.
I want to know why, please help me.
