12 Feb 2013 waitbar with time estimation Estimated remaining, elapsed time, and percentage complete. Author: Andrew

Great job. Thanks.
A little improvement for compatibility: in Matlab's original waitbar, the 'message' string is optional for the first call:
h=waitbar(0);
With your function it makes an error.
30 Jan 2013 grdread2 Uses built-in netCDF capability to load a grid file created by GMT (Generic Mapping Tools) v3 or v4 Author: Kelsey Jordahl

Works perfectly with a huge .grd DEM. Thanks very much for this effort.
23 Jan 2013 Okada solution Computation of co-seismic displacements due to a rectangular dislocation in an elastic half-space. Author: Denys Dutykh

Hi Denys,
Nice and effective function.
If you need open mode fault and compute all the tilt and strain components, see my submission at http://www.mathworks.com/matlabcentral/fileexchange/25982
Regards,
François.

02 Dec 2012 DEM: Shaded relief image plot (digital elevation model) Pretty shaded relief map as flat image. Author: François Beauducel

Hi Carlo,
To add the colorbar you need to use the dem(...,'scale') option. Type doc dem to get all the available options.
François.

09 Nov 2012 GREATCIRCLE and LOXODROME: "As the crow flies" and rhumb line path, distance and bearing Computes path coordinates, distance and bearing on Earth along great circle or rhumb line. Author: François Beauducel

Note: update on Nov. 9, 2012 concerns only the loxodrome function: now it uses an exact calculation of bearing angle (using the Gudermann function).

13 May 2013 Round with significant digits Rounds towards the nearest number with N significant digits. Author: François Beauducel Will

Does not work in all cases. Try rounding 3.55 to 1 decimal place and you get 3.5 instead of 3.6
10 Apr 2013 READHGT: Import/download NASA SRTM data files (.HGT) Imports or download SRTM worldwide digital elevation model data files. Author: François Beauducel Jeff

Regarding my previous comment, I just now noticed you recently added the 'crop' argument update which is exactly what I needed. You are way ahead of me... Amazing what a little bit of reading can do :) Thanks.
27 Mar 2013 Okada: Surface deformation due to a finite rectangular source Computes Okada's 1985 solution for displacements, tilts and strains due to fault dislocation. Author: François Beauducel zhou, hui

Hello,I'am puzzled about how to get E,N when the code is used for InSAR measurements:
[uE,uN,uZ] = okada85(E,N,14000,193,24,600000,200000,81,11.0586,0) ;
Thank you
13 Mar 2013 DEM: Shaded relief image plot (digital elevation model) Pretty shaded relief map as flat image. Author: François Beauducel Massin, Fred

This is great to be able (finally!) to export vector shaded image with matlab, thank you!

veru good
