Or, alternatively, try my newborn plotdecimate.m, available at
 <http://fly.isti.cnr.it/pub/software/octave/plotdecimate.m>.
It works on only one plot line at a time, so if you want to plot many
graph lines, you should use it on all lines one by one before plotting.

Suggestions for improving the API are gratefully accepted.

plotdecimate is the user-defined function from the file
/home/pot/math/octavelib/graph/plotdecimate.m

 -- Function File:  plotdecimate (P)
 -- Function File:  plotdecimate (P, SO)
 -- Function File:  plotdecimate (P, SO, RES)
     Optimise plot data by removing redundant points and segments

     The first parameter P is a two-column matrix to be plotted as X and
     Y coordinates.   The second optional argument SO disables segment
     optimisation when set to FALSE (default is TRUE). The third
     optional argument RES is the size of the largest error on the plot:
     if it is a scalar, it is meant relative to the range of X and Y
     values (default 1e-3); if it is a 2x1 array, it contains the
     absolute errors for X and Y.  Returns a two-column matrix
     containing a subset of the rows of P. A line plot of P has the
     same appearance as a line plot of the output, with errors smaller
     than RES.  When creating point plots, set SO to FALSE.
