13 Jan 2011 Accurate Fast Marching Multistencils second order Fast Marching 2D and 3D including rk4 shortest path and skeletonize Author: Dirk-Jan Kroon

Can you provide the m files of the c code? Some of us do not have matlab compiler.
20 Oct 2010 Legendre Laguerre and Hermite - Gauss Quadrature Nodes and weights for Legendre Laguerre and Hermite - Gauss Quadrature Author: Geert Van Damme

One addition I did is this

% Linear map from[-1,1] to [a,b]
x=(a*(1-x)+b*(1+x))/2;
w=(b-a).*w/2;

a and b are user provided, and I think now that you can shift from [1 1] to [a b]

Very useful program.

How can I calculate the GaussLegendre in the [0 1] space?
11 Oct 2010 Color Palette Tables (.cpt) for Matlab Create and apply GMT-style colormaps in Matlab Author: Kelly Kearney

Hi. Very nice package. Is it possible to use the inverse colormap of GMT_seis.cpt?
06 Jun 2010 MESH2D - Automatic Mesh Generation Generates unstructured triangular meshes for general 2D geometry. Author: Darren Engwirda

Why the following fails with meshfaces. I can run it with mesh2d

 node = [0.0, 0.0; 1.0,0.0; 1.0,1.0; 0.0,1.0; 2.0,0.0; 2.0,1.0; 3.0,0.0; 3.0,1.0];
 edge = [1,2; 2,3; 3,4; 4,1; 2,5; 5,6; 6,3; 5,7; 7,8; 8,6];
faces{1} = [1,2,3,4];
faces{2} = [5,6,7,2];
faces{3} = [8,9,10,6];
hdata.edgeh=[1,0.05 ;7,1];
 [p,t]=mesh2d(node,edge,hdata);
%[p,t,fnum]=meshfaces(node,edge,faces,hdata);

running it with meshfaces

??? Index exceeds matrix dimensions.
