public class DFT
extends AbstractJAIFlattener

Performs discrete fourier transform (DFT).

Valid options are:

-D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to 
    the console (0 = off).
    default: 0
    minimum: 0
 

-field <adams.data.report.Field> [-field ...] (property: fields)
    The fields to add to the output.
    default: 
 

-notes <adams.core.base.BaseString> [-notes ...] (property: notes)
    The notes to add as attributes to the generated data, eg 'PROCESS INFORMATION'
    .
    default:
