Inputs/Outputs

  • ccclst.png WP session —

    WP session specifies a reference to an existing wavelet packet structure.

  • cu64.png ref —

  • catrn.png t0 —

  • cdbl.png dt —

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • icclst.png WP session out —

    WP session out returns a reference to an existing wavelet packet structure, which this VI can modify.

  • iu64.png ref —

  • iatrn.png t0 —

  • idbl.png dt —

  • i1di32.png node index —

    node index returns the indexes of the terminal nodes of the wavelet packet tree indexed from top to bottom and left to right.

  • i1dstr.png path —

    path returns the paths associated with the terminal nodes in node index.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
