I have a 2xn matrix describing a geologic transect in terms of position (in meters) and height (in meters). I would like to smooth this to remove (smooth over) small wavelength topography. How do I do this?

Use smooth1q on the File Exchange (<http://www.mathworks.com/matlabcentral/fileexchange/37878-quick---easy-smoothing>) by Damien Garcia. For my data of over a thousand points, I needed smoothing of about 1e5 to 1e6 (100000 to 1000000).
