OCEAN and manipulating a waveform

    Hi!

    I have a waveform and want to set all y-values of the waveform which are
    negative to 0.

    Any hints on how I can accomplish this task easily with OCEAN?

    Thanks for any help!

    If the waveform is in a variable a, a simple way is to do:

    (abs(a)+a)/2.0

    To get the positive parts set to 0, it would be:

    (abs(a)-a)/2.0

    Simpler than messing around with all the points, but it doesn't interpolate at
    zero crossings, so it may not be exactly what you want...

    Andrew.
