You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.

function will be evaluated
%              at K evenly spaced rotations from -Pi/4 to Pi/4. For
%              small data sets (less than a few hundred points), the
%              default value of 150 should work well. For larger data
%              sets, very small benefits may be realized by
%              increasing the value of K, but keep in mind that the
%              algorithm is linear in K.
%
%    AUG_FLAG: This flag is set to 1 by default, which indicates
%              that the data set will be "augmented" as discussed
%              in the paper. If this flag is set to 0, then the
%              data will not be augmented, and the next two 
%              arguments are meaningless. For large data
%              sets with more than 10000 points, this flag should
%              usually be set to 0, as there is usually no need to
%              augment the data in these cases.
%
%    reps:     This is the number of replicated points for each  
%              original point. The default value is 30. The larger
%              the number of points in the data set, the smaller
%              this value can be. For data sets of 10,000 points or
%              more, point replication should be de-activated by setting
%              AUG_FLAG to 0 (see above).               
%
%    stdev:    This is the standard deviation of the replicated points. I
%              can't give too much guidance as to how to set this
%              parameter, but values much larger or smaller than
%              the default don't seem to work very well in the
%              experiments I've done.
