STFTB - Scilab Time Frequency Toolbox
------------------------------------------------------------------
TODO:
With version 2.0.3 on Scilab 6.1.1:
* Caf2tfr: since 6.1.0, its output is mandatory. It should not.
* Ctfrdist: since 6.1.0, its output is mandatory. It should not.
* Chtl: unit test fails (already with Scilab 6.0.2)(tolerance on result)
------------------------------------------------------------------

2.0.4 - Obsolete calls to xset and remaining printf removed (slint run)(2023.0)
      - packaging changed to (try to) cope with atomsInstall()

2.0.3 - Obsolete calls to printf, sprintf and mfprintf replaced with
        mprintf, msprintf, mfprintf (slint run)
      - Help pages improved:
        - Code style in synopses and examples
        - See also now with short descriptions
        - Various fix and improvements: codes out of their programlisting
          or image tags, duplicated paragraphs removed, grayplot in examples
          now with gca().tight_limits="on", ..
		- 1st PDF version released. Thanks to Calibre FOSS.

2.0.0 - sci_gateways rewritten for Scilab-6
         + Parameter checking improved 
         + Ctfrxxx and tfrxxx functions made equivalent when signal is a
           single vector
         + Ctfrrsp and tfrrsp modified to work with rectangular windows.
         + calling sequence of reassigned.c modified to add one more
           argument (Threshold)
         + tfrgrd, the Scilab sinc function is sin(x)/x while the Cstftb
            one is sin(%pi*x)/(%pi*x)
         + Ctfrbj, Ctfrbud when Nfreq==N and is odd
         + Chtl : the (1,1) element was not computed
     
      - triang, hamming, hanning, nutall, blackman, harris, barthann,
        papoulis windows definition changed in tftb_window and Cwindow
        according to the
        en.wikipedia.org/wiki/Window_function#Hann_and_Hamming_windows
        pages.
      - Kaiser ans Nutbess windows added in Cwindow.
      - Hanna window (no definition found) replaced by power of Sine window

      - Matlab compatibility functions (mtlb_*) replaced by the Scilab
         equivalents
      - Help page examples verified and graphical outputs included
      - bug fixes

1.2.1 - help structure is changed and Chapters are added

1.2   -  some bugs are removed
      -  sci_gateway added (Ctftb was ported to scilab)
      - new demos

1.1.1 - some bugs are removed

1.1   - some bugs are removed
      - tftb_window can be plotted 
      - frspec and frpowerspec added
