22 Aug 2011 Export triangulation to Paraview Function to export an unrestricted 2D triangulation to a VTK file which can be open with Paraview. Author: David Gingras

Hi Luke, exportTriangulation2VTK.m just deals with 3D shell meshes (assembly of triangles not tetrahedra). If you do have a shell mesh and you are not able to export it to Paraview, you can send me your code and I'll see what I can do. Cheers. - David

21 Jul 2009 m-code to LaTeX converter This m-file (with GUI) converts m-code into a tex-file for including in a LaTeX-document. Author: Uwe Lelke

Very useful and it works at the first time! I got a small error with an equation with 2 transposes in the same line (e.g. : G=P*C'/(C*P*C'+R)). The parser has interpreted the code between both transposes (') as a string. But it's minor. Good job, thanks!

24 Jun 2009 ESTIMATION PROCESS USING NON LINEAR ENERGY OPERATOR ESTIMATION OF AM SIGNAL USING NLE Author: Tamal Das

Useful for understanding. Thanks! Suggestion : use vectorized operators for discrete derivatives instead of loop.

28 May 2009 Inhull Efficient test for points inside a convex hull in n dimensions Author: John D'Errico

Another very usefull code provided by John! Thanks.

25 Nov 2008 gridtrimesh Fits a square grid surface of the form z = f(x,y) to a triangular mesh surface. Author: Willie Brink

Very nice and fast!
This function takes care of non-convex surface with holes.
Good job!

28 Aug 2013 Export 3D line to Paraview Function to export a 3D line to a VTK format which can be open with Paraview. Author: David Gingras Farhi, Emmanuel

Export a single line to a VTK set of points. Good job.

Very useful, thank you.

nice work, it works!

15 Aug 2011 Export triangulation to Paraview Function to export an unrestricted 2D triangulation to a VTK file which can be open with Paraview. Author: David Gingras Luke

David, I have a 3D point cloud that I am running through delaunay(x,y) on and this generates a nx3 matrix, n being the # of triangulations. I am using this to create a smooth surface in MATLAB that can accurately model the point cloud if it were a volume, not just points. When I load the VTK file into Paraview, the triangulations are not working well and Paraview makes the file look more like a surf plot rather than a triangulation. Any suggestions as to what I am doing wrong?
