26 Jul 2013 OKUBO: Gravity change due to shear and tensile faults Okubo's 1992 model for gravity change due to finite rectangular source in elastic half-space. Author: François Beauducel

Dear Martin,
Thanks for your feedback. The modification you made makes the function compatible with older version of Matlab (before 2009b, probably yours ?), but it adds warnings of the code analyser message indicator for any newer versions...
Anyway, I prefer to extend the backward compatibility so I will include your update.
Thanks again.
François.

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.

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

12 Jul 2013 OKUBO: Gravity change due to shear and tensile faults Okubo's 1992 model for gravity change due to finite rectangular source in elastic half-space. Author: François Beauducel Fuchs, Martin

I modified the scrip, now it works also for mee:
remove all ~ add dummy parameter:

function u=Sg(xi,eta,q,dip,nu) % dip,~)
function u=Dg(xi,eta,q,dip,nu) % dip,~)
function u=Tg(xi,eta,q,dip,nu) % dip,~)
function u=Cg(xi,eta,q,dip,nu) % dip,~)
function I=I2(xi,eta,q,R,nu) % dip,~)

regards Martin

10 Jul 2013 OKUBO: Gravity change due to shear and tensile faults Okubo's 1992 model for gravity change due to finite rectangular source in elastic half-space. Author: François Beauducel Fuchs, Martin

I have problems using the code it says:

?? Error: File: okubo92.m Line: 249 Column: 28
Unexpected MATLAB operator.

When I look at this line I see:
function u=Tg(xi,eta,q,dip,~)

maybe the ~ is problematical

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

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.
