Is there a M file to make laplace space filters rather than Z space filters?

You just need to skip the bilinear command in butter.m.  How
about checking for a file arg of 's' on the command line and using
that to decide if you are going to call bilinear.  Patches for butter,
cheby1, cheby2 and ellip will be much appreciated.
