 2022-03-17  Brouard Nicolas  <brouard@ined.fr>          successfully the praxis C version of Buckhardt.  But Buckardt's
           version was difficult to read and Gegenfurtner's version had a few

         * imach.c (Module): Still bugs in the result loop. Thank to Holly Benett          from Golub. I used the recent "awe" compiler from Gkynn Webster.
           The awe library had errors, for example in arc tangent function
 *2021-03-08  Nicolas Brouard   <brouard@ined.fr>          which have been fixed.
   
         * ./ (Module): Fixed bug on result:          The main objective was to get identical results with the three
           versions: (1) Algol W, (2) Buckhardt'C version as well (3)
 *2021-02-20  Nicolas Brouard   <brouard@ined.fr>          Gegenfürtner C versions on the various test functions published by
           Brent in 1973 in Algol W.
         * imach.c (Module): Fix bug on quitting after result lines!  
         (Module): Version 0.99r21          Also, in order to compare them, the random function had to produce
           the same sequence for the 3 softwares. The random function used in
 2021-02-12  Nicolas Brouard   <brouard@ined.fr>          imach corresponds to original Brent's random function written in
           Algol W.  Other point, in Algol W, the arrays of dimension n are
         * imach.c (Module): The use of a Windows BOM (huge) file is now an error          'normal' mathematical arrays starting from 1 to n. But this is a
           real issue in C where, by default, arrays are starting from 0 to
           n-1. In Buckhardt, as well as in Gegenfürtner C code, it can be
 2021-02-11  Nicolas  Brouard   <brouard@ined.fr>          seen that authors while trying to mimick original Brent Algol W
           code are hesitating by changing either a loop originally from 1 to
         *  (Module): imach.c Someone entered 'results:' instead of 'result:'. Now it is an error which is printed.          n in a loop from 0 to n-1, or keeping Brent's loop from 1 to n and
           shifting the index from original X(I) in Algol W to x[i-1] in C.
 2020-02-22  Brouard Nicolas  <brouard@ined.fr>          But as IMaCh is using, since the beginning, the Numerical Recipes
           functions vector or matrix, I changed Geggenfürtner code to mimick
         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          the original Algol W arrays. Thus the X(I) is translated in C as
         and life table from the data without any state)          x[i] which minimizes the errors. The Golub QR algorithm was
           published in Algol with overflow errors which were reproduced in
 2019-05-20  Brouard Nicolas  <brouard@ined.fr>          Brent's Algol W code. Buckhardt code fixed these errors which are
           much more problematic in C than in Algol W.  Thus Buckhardt code
         * version.h: Summary: version 0.99.r19          seems very safe, but i haven't chosen it for IMaCh because the C
           style is horrible and almost unreadable compared to Gegenfürtner
         * imach.c: Summary: Projection syntax simplified          CO code which is very close to Brent's original. Also what makes
         We can now start projections, forward or backward, from the mean date          Buckhardt code more difficult to read is, instead of passing the
         of inteviews up to or down to a number of years of projection:          minimum of parameters in the functions calls, as it is in Algol
         prevforecast=1 yearsfproj=15.3 mobil_average=0          Brent's code or Gegenfürtner's code, the list of parameters is
         or          high. For example, the flin function LONG REAL PROCEDURE FLIN
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0          (LONG REAL VALUE L) has only one parameter in Algol W, the
         or          Gegenfürtner flin function had two parameters: static double
         prevbackcast=1 yearsbproj=12.3 mobil_average=1          flin(l, j) double l; { int i; double tflin[N];} but Buckhardt
         or          function has 14 parameters which makes the code unreadable and
         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          useless. Gegenfürtner used a lot of static variables or functions
           which I tried to minimize. Also in Gegefürtner, array dimensions
 2019-05-18  Brouard Nicolas  <brouard@ined.fr>          were fixed to N. In my adaptation the flin is static double
           flin(double l, int j) and the parameter used are global variables.

 2017-07-17  Brouard Nicolas  <brouard@ined.fr>          use the first covariate V1 into the model but in fact they are
