- ****************************************************************************
- Changes for IDL Wavelet Toolkit 6.1
- ****************************************************************************
-
- o Change version number to match IDL's version.
- o Remove license restriction from:
- WV_CWT
- WV_DWT
- WV_FN_COIFLET
- WV_FN_DAUBECHIES
- WV_FN_GAUSSIAN
- WV_FN_HAAR
- WV_FN_MORLET
- WV_FN_PAUL
- WV_FN_SYMLET
- WV_PWT
- You no longer need a license to run the core wavelet analysis routines.
- A license is only needed for the GUI routines:
- WV_APPLET
- WV_PLOT3D_WPS
- WV_PLOT_MULTIRES
- WV_TOOL_DENOISE
-
-
- ****************************************************************************
- Changes for IDL Wavelet Toolkit 1.6
- ****************************************************************************
-
- o Fix WV_CWT so it doesn't convert complex input to real.
- o Added tooltips to buttons.
-
-
- ****************************************************************************
- Changes for IDL Wavelet Toolkit 1.5
- ****************************************************************************
-
- Bug Fixes
- ---------
- o DSCALE, NSCALE and START_SCALE keywords were not accepted by WV_CWT.
- They now work correctly.
- o If a data field contains a negative number that requires scientific
- notation, the format string could overflow. Fixed.
- o WV_DWT/WV_PWT would crash if passed a temporary variable, and then
- the result was made into a temporary. Don't free a temporary twice.
- o In WV_DENOISE, if neither COEFFICIENTS nor PERCENT were input, then
- only one coefficient was being retained, rather than all of them. Fixed.
- o In WV_PLOT3D_WPS, for 1D vectors with length not a power of two, the
- extra padding was not being removed after computing the discrete
- transform. Wasn't a problem for the continuous transform.

- ****************************************************************************
- Changes for IDL Wavelet Toolkit 1.4
- ****************************************************************************
-
- New Functions
- -------------
- Command Description
- WV_CWT Returns the one-dimensional continuous wavelet transform
- of the input array. The transform is done using a
- user-inputted wavelet function.
- WV_DENOISE Uses the wavelet transform to filter (or de-noise) a
- multi-dimensional array.
- WV_FN_GAUSSIAN Constructs wavelet coefficients for the
- Gaussian wavelet function.
- WV_FN_MORLET Constructs wavelet coefficients for the
- Morlet wavelet function.
- WV_FN_PAUL Constructs wavelet coefficients for the
- Paul wavelet function.
-
-
- New and Updated Keywords/Arguments
- ----------------------------------
- WV_APPLET
- Input: This argument can now either be a string representing a
- save file to open, or an array of data.
-
- WV_CW_WAVELET
- DISCRETE: Set this keyword to include only discrete wavelets
- in the list of wavelet functions. Set this keyword to zero to
- include only continuous wavelets.
- The default is to include all available wavelets.
- NO_COLOR: If this keyword is set, the wavelet functions will be
- drawn in black and white.
- NO_DRAW_WINDOW: If this keyword is set, the draw window will not
- be included within the widget.
- VALUE: Set this keyword to an anonymous structure of the form
- {FAMILY:'', ORDER:0d} representing the
- initial value for the widget.
-
- WV_PLOT3D_WPS
- Input: This argument can now either be a string representing
- the file to open, or an array of data.
- SURFACE_STYLE: Set this keyword to an integer specifying the
- initial style to use for the three-dimensional surface.
- Valid values are:
- 0 = Off
- 1 = Points
- 2 = Mesh
- 3 = Shaded
- 4 = XZ lines
- 5 = YZ lines
- 6 = Lego
- 7 = Lego fill
-
- Bug Fixes
- ---------
- o Visualize --> Wavelet Power Spectrum does not work on Mac.
- Problem was due to duplicate line of code.
- o Wavelet Toolkit won't start if an undefined procedure/function exists.
- Problem was due to RESOLVE_ALL within WV_APPLET.
- o Change File-->Open error message to state that file is not a
- valid Wavelet save file.
- o Changed the Haar offset parameters from ioff=joff=0 to ioff=joff=1,
- to match those for Daubechies order=1.
- o Allow user to input multiple columns of an ASCII file as either
- separate time series or a 2D array. If first column has the name "time"
- then it is assumed to be the independent variable.
- o Make data changes, then Select File-->Exit. The "Cancel" button now
- returns user to the applet rather than exiting.

- ****************************************************************************
- Changes for IDL Wavelet Toolkit 1.0
- ****************************************************************************
-
- Version 1.0 was the initial release, and shipped with IDL 5.3.
- There were no version numbers 1.1-1.3.
- The next version was IDL Wavelet Toolkit 1.4.
