###
Widget Commands and Visualization Tools

WV_APPLET - Runs the IDL Wavelet Toolkit GUI.

WV_CW_WAVELET - Compound widget used to select and display wavelet functions.

WV_IMPORT_DATA - Allows user to add a variable to the currently active WV_APPLET widget from the IDL> command prompt.

WV_IMPORT_WAVELET - Allows user to add wavelet functions to the IDL Wavelet Toolkit.

WV_PLOT3D_WPS - Runs the GUI for 3D visualization of the wavelet power spectrum.

WV_PLOT_MULTIRES - Runs GUI for multiresolution analysis.

###
Wavelet Transform

WV_CWT - Returns the one-dimensional continuous wavelet transform of the input array.

WV_DENOISE - Uses the wavelet transform to filter (or de-noise) a multi-dimensional array.

WV_DWT - Returns the multi-dimensional discrete wavelet transform of the input array.

WV_PWT - Returns the partial wavelet transform of the input vector.

###
