SUOP - Unary Arithmetic Operations on SU Data

Occassionally we want to apply mathematical functions or other operations which go beyond gaining to data. Such operations might include

Operations involving logarithms are ``punctuated'' meaning that if the contains 0 values, 0 values are returned.

Examples of suop using SU plane data may be easily run

% suplane | suaddnoise > data.su
% suop < data.su op=abs | suxwigb title="absolute value" &
% suop < data.su op=ssqrt | suxwigb title="signed square root" &
% suop < data.su op=sqr | suxwigb title="signed square" &
...

Please type:

% suop
