Le premier permet de savoir à chaque nouvelle Release de MATLAB les fonctions qui sont ou qui vont être supprimées , obsolètes , non documentées … d’où le nom de whatsold qui fait l’inverse de la fonction whatsnew shippée avec MATLAB.
Le second « Send email using CDO » permet d’envoyer des mails depuis MATLAB en utilisant votre messagerie Microsoft Outlook . Avec l’avantage que le nom de celui qui envoie le mail peut être modifié. J’en parlerai plus longuement dans un autre post.

Donc si on lance whatsold en R2010b , on aura ces informations suivantes dans un log :

Si je relance whatsold dans la Prerelease R2011a je vais avoir un nouveau log.
Ce que j’ai fait ensuite c’est de comparer en utilisant la fonction visdiff le résultat des logs R2010b et R2011a.

On apprend ainsi :

• Message qui apparaissait en 10 b et qu’on ne trouve plus en 11a

intwarning: INTWARNING will be removed in a future release.

• Nouveaux messages en R2011a:

Les fonctions qui n’existent plus en R2011a :

ipttable: IPTTABLE has been removed. Use UITABLE instead.
cholinc: CHOLINC will be removed in a future release. Use ICHOL instead.
cholinc: CHOLINC(X,’inf’) will be removed in a future release.
luinc: LUINC will be removed in a future release. Use ILU instead.

Les nouvelles fonctions en R2011a non-documentées:

primitivevertexpicker: This function is undocumented and may change in a future release.
contours: This undocumented function may be removed in a future release.
makebars: This undocumented function may be removed in a future release.
figureDefaultMenubar: This function is undocumented and will change in a future release.
figureDefaultToolbar: This function is undocumented and will change in a future release.

Hum hum intéressant tout ça …
Les 2 dernières fonctions non docuementées font ce que leur nom indiquent:

figureDefaultMenubar : Create default toolbar.
figureDefaultToolbar : Create default menus.

Quant aux autres voilà ce qu’on lit dans le Header du M-file:
MAKEBARS : Make data for bar charts.
CONTOURS : Contouring over non-rectangular surface.

PRIMITIVEVERTEXPICKER un peu compliqué à mon gout pour en parler!

Dans les releases notes de la R2011a , au chapitre Desktop Tools and Development Environment, MATLAB Version 7.12 (R2011a) on peut lire :

Filter Results in Folder Comparisons

You can now define filters to exclude unimportant differences when comparing folders. For example, you can exclude backup files or files created by a revision control system. Filters can save time when reviewing differences, especially when comparing many subfolders.

• Exemple

Concrètement imaginons que je veuille comparer les répertoires \matlabroot\extern\examples\mex de la R2010b et de la R2011a:
sur ma machine en ligne de commande cela revient à taper:

>> visdiff(‘C:\Program Files\MATLAB\R2011a\extern\examples\mex’,’C:\Program Files\MATLAB\R2010b\extern\examples\mex’)

Pour info , ces répertoires donnent des exemples pour apprendre à écrire des MEX-files en C ou en Fortran.

et voilà ce que j’obtiens dans le Comparison Tool :

Seul un fichier est différent c’est le fichier binaire explore.mexw32 qui est un MEX file compilé à partir de l’exemple explore.c.
Évidemment comparer des fichiers binaires n’a pas de sens. Donc à partir de la R2011a il est possible de filtrer les résultats dans l’outil de comparaison.

• Petite parenthèse sur explore.c

Ra je ne peux pas m’empêcher de vous parler de ce fichier qui est fort utile, non seulement pour écrire des Mex-files mais aussi pour comme son nom l’indique explorer ses variables MATLAB : structure , cellule , valeurs numériques, chaines de caractères … Par exemple imaginons que je crée la structure suivante :

>> aurelien.age=31

aurelien =

age: 31

>> aurelien.passion=’matlab’

aurelien =

age: 31
passion: ‘matlab’

Si je lance explore dans MATLAB , ce qui va marcher car il a été mexé sous Windows comme on dit dans le milieu geek , j’obtiens :

>> explore(aurelien)

————————————————
Name: prhs[0]
Dimensions: 1×1
Class Name: struct
————————————————

(1,1).age
————————————————
Dimensions: 1×1
Class Name: double
————————————————
(1,1) = 31

(1,1).passion
————————————————
Dimensions: 1×6
Class Name: char
————————————————
(1,1) matlab

C’est pas génial ça?!!!

• Et maintenant utilisons le filtre!

En cliquant sur le bouton:

apparait cette petite interface qui me permet de rajouter un filtre:

je vais pouvoir ajouter mon filtre *.mexw32 en cliquant sur le bouton + :

ce qui me rajoute un troisième élément à ma liste d’extension à exclure:

En cliquant sur OK, les changements prennent effet immédiatement. Et on voit que le mex file est à présent ignoré dans la comparaison:

Voilà moi je trouve ça super comme nouvelle fonctionnalité , encore une bonne raison d’upgrader en R2011a!
