title: High-pass filtering in MATLAB
body: <p>Does anyone know how to use filters in MATLAB?
  I am not an aficionado, so I'm not concerned with roll-off characteristics etc — I have a 1 dimensional signal vector x sampled at 100 kHz, and I want to perform a high pass filtering on it (say, rejecting anything below 10Hz) to remove the baseline drift.</p>
  
  <p>There are Butterworth, Elliptical, and Chebychev filters described in the help, but no simple explanation as to how to implement.</p>
