Can anybody tell how I should proceed to filter out some "spikes"
from a vector of data using Octave?

If I visualize the vector I can see its basically regular structure which
is disturbed by some zig-zags which I would like to eliminate (mainly to
be able to find meaningful extrema of the basic structure).
