[CSC 335] The pesky complex components...

[Andrew J. Pounds]

Some of you have noticed that after you recover the filtered y-array 
that almost all of the complex components are non-zero. You will most 
likely find that these values will differ significantly between arrays 
recovered using the inverse matrix method vs. the direct linear algebra 
method.   Here is the good news -- those values can be thrown away when 
you actually plot the array as you are only interested in the real 
components for this exercise.  Don't misunderstand -- you MUST have them 
for the filter to work as they are part of the DFT processing -- but 
once the filtering is done all you need are the real components.
