thanks Daniel.

31 May 2014 Read and write multiplexed miniSEED file Imports and exports data files in seismological format "mini-SEED" Author: François Beauducel

The problem detected by Robert is solved. Number of plotted channels in multiplexed files is now limited to 20 subplots, with a warning message. For larger number of channels, please use the functional form [X,I]=rdmseed(...) to load and plot what you want (see help).

28 Feb 2014 LL2UTM and UTM2LL Latitude/longitude to and from UTM coordinates precise and vectorized conversion. Author: François Beauducel

This vectorized version of lat/lon vs UTM coordinates conversion may help users to deal with huge grids like digital elevation models, where others functions fail or take infinite time.

Thanks.

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.

MATLAB MASTER!

Thank you very much for this submission.
This is an awesome tool.

Chapeau.

Hello, when running the a miniSEED file from the NCEDC, I recieve the error "Error using cat. Dimensions of matrices being concatenated are not consistent" (Line 284) Does anyone have any advice or help to offer? Thanks!

Great tool, definitely useful!

I discovered one issue when downloading hgt files of North America data at all latitudes above 54°N.

On the USGS website these files are not in the *.hgt.zip format, and are instead *hgt.zip (no decimal point before hgt).

Therefore line 236 in 'readhgt.m' fails for these latitudes:
k = find(~cellfun('isempty',strfind(idx{1},ff)));

I changed this line to:
k = find(~cellfun('isempty',strfind(idx{1},ff(1:end-8))));

which works, but might not be the most elegant!
