23 Jul 2009 MRI Analyze tools Read/View Analyze data format (MRI). Author: Darren Weber Henrie, Brad

Extremely well made. Finding these files has saved me 2 weeks of programming.

27 Jun 2008 MRI Analyze tools Read/View Analyze data format (MRI). Author: Darren Weber Bai, Wenjia

Very helpful for writing Analyze 7.5 format.
16 Nov 2007 Mesh Laplacian Calculate Laplacian for triangulated mesh. Author: Darren Weber Hanselman, Duane

A function should not produce command window output unless there is warning or error feedabck. Let the user place tic and toc around the function rather than include them in the function itself. Get rid of:

fprintf('MESH_LAPLACIAN: Calc Laplacian matrix for %5d vertices...',nvertex);
tic
...
t = toc;
fprintf('done (%6.2f sec).\n',t);

Can you describe the input arguments or revise them to match the way MATLAB uses triangulation, e.g., from TRIMESH
% TRIMESH(TRI,X,Y,Z,C) displays the triangles defined in the M-by-3
% face matrix TRI as a mesh. A row of TRI contains indexes into the X,Y, and Z vertex vectors to define a single triangular face.
11 May 2007 Mesh Laplacian Calculate Laplacian for triangulated mesh. Author: Darren Weber cnkf, yuga

|Fr|Le maillage, c'est juste un tableau de coordonnées (vertex).

Généralement on utilise un générateur d'objets 3D (comme Lynx) qui crée un fichier texte avec les coordonnées des points et les numéros de ces points qui sont reliés dans une face.

Tu peux aussi essayer la fonction GenMesh de Matlab.
