SYMASYM_FFT

SYMASYM_FFT

Name


      SYMASYM

Purpose


      Resolve an array into symmetric & anti-symmetric components.

Category


Calling Sequence


      symasym, in, sym, asym

Inputs


      in = input array (1-d or 2-d). in

Keyword Parameters


Keywords


        /X means do symmetry/antisymmetry in X dimension.
        /Y means do symmetry/antisymmetry in Y dimension.
            These keywords only apply to 2-d data.

Outputs


      sym = symmetric component of in. out
      asym = anti-symmetric component of in. out

Common Blocks


Notes


      Notes: The sym/asym components for 2-d arrays are by
        default radially symmetric/antisymmetric from the array
        center. Use the keyword /X or /Y to force resolution
        in a single dimension.
