Cheby1 filter
WebGenerate a Chebyshev type I filter with rp dB of passband ripple. [b, a] = cheby1 (n, Rp, Wc) low pass filter with cutoff pi*Wc radians.

No, both outputs of filter and filtfilt are correct, of course. But the results can differ from your expectations. Remember that filtfilt tries to reduce transitional effects at the start and end of the signal.
