Very impressive piece of code.

This is awesome, I have been looking for such a code for a such a long time. Congrats.

31 Dec 2010 Automatic Differentiation for Matlab This package provides automatic first and second derivatives for vector-functions and matrices. Author: Martin Fink

21 Dec 2010 Toolbox Fast Marching A toolbox for the computation of the Fast Marching algorithm in 2D and 3D. Author: Gabriel Peyre

IMPORTANT:

1) The code for the anisotropic propagation is not included anymore in the toolbox, so do not try to compile it. Contact me if you *really* need anisotropic propagation.

2) Although this toolbox works fine, it is not "plug and play". If you want an introduction to Fast Marching method, you should try my Numerical Tours

19 Dec 2014 Toolbox Graph A toolbox to perform computations on graph. Author: Gabriel Peyre Helen

As others have pointed out, the compute_curvature function results in an index out of bounds error in some cases. So far, my untested and kind of random 'fix' was to comment out the code

%normal = normal'; (line 72) and
insert it again as
normal = normal'; (at line 146, after compute_normal()).

This seems to avoid the out of index error BUT I have no idea if it a right thing to do otherwise.

Some support from Gabriel, would be highly appreciated.

Thanks a lot for your efforts

(on line 75 "dp = sum( normal(:,E(:,1)) .* normal(:,E(:,2)), 1 );")

12 Dec 2014 Toolbox Fast Marching A toolbox for the computation of the Fast Marching algorithm in 2D and 3D. Author: Gabriel Peyre dhara

great toolbox... but i am facing problem with compile mex file.plz anyone help me out...

Error: Error using mex
unable to complete successfully.
i dont have much ide about compile c file in matlab also..may be it is my error but plz help me.

Thanks for this library.

Just spent quite some time tracking down the same bug in `write_ply.m` as Chris Rorden found a year ago. Please fix it.

07 Nov 2014 Toolbox Fast Marching A toolbox for the computation of the Fast Marching algorithm in 2D and 3D. Author: Gabriel Peyre Seung-Goo

Thank you for sharing a seemingly great toolbox. But like some users, I also failed to compile mex files. Although I don't intend to use "perform_front_propagation_anisotropic", it calls an error:
Unable to complete successfully.

Error in compile_mex (line 7)
mex mex/anisotropic-fm//perform_front_propagation_anisotropic.cpp

leaving perform_front_propagation_mesh, which I wish to use, not compiled.

So I just commented the line 7 in "compile_mex.m", which reads "% mex mex/anisotropic-fm//perform_front_propagation_anisotropic.cpp".

Then compile_mex.m returns a bunch of warnings but it ends without errors. and the functions seem to work, I guess. I wish the author update/modify the compile_mex.m to bypass such errors, and hope this helps others having this error, although I'm not sure if this introduces some insane behaviors or not.
