09 Aug 2011 plotboxpos Returns the position of a plotted axis region Author: Kelly Kearney

Very useful function, thanks.
It's missing only a little test like:

if nargin < 1
   h = gca;
end

and your function becomes perfect !
Thanks again.
25 Jul 2011 Fluke .IS2 file reader Simple function for reading out data from Fluke Thermal Imager -IS2 files. Author: Magnus Andersen

Hi,

I need to load IS2 file from a TI32 instrument... your script is not exactly adapted to it but it was an essential start for understanding Fluke file format. So many thanks for that!

FYI, the visible image is not a grayscale but a RGB coding in 5:6:5 bits. So to get a color image from your 16-bit matrix vis, you just have to type:
v = zeros([480,640,3],'uint8');
v(:,:,3) = bitshift(bitand(vis,31),4); % 5 less significant bits = blue
v(:,:,2) = bitshift(bitand(bitshift(vis,-5),63),3); % 6 middle bits = green
v(:,:,1) = bitshift(bitshift(vis,-11),4); % 5 most significant bits = red
imagesc(v)

I will continue this work and probably submit a script adapted to TI32 files in the next days. As you I will try to get some of the metadata (I only need date, time and emissivity value).

If you think it may be of any interest, I may adapt the script to read TI10 files also...

Regards,

François.
23 Sep 2010 Reading mini-Seed m-files for reading mini-Seed files with STEIN-1 or STEIN-2 compression protocol. Author: Ljupco Jordanovski

Hi.
It is a very useful effort that you made with these functions, and I was very surprised there is no other attempts on the Web about this...

Unfortunately, I didn't get success in using your function with my miniSEED files... I spent some time to look at your scripts, but finally wrote my own function "rdmseed.m" (submitted this day to Matlab Central). My code is totally rewritten (especially STEIM decoding), also because I needed to access all block headers of individual records; but somehow my function is partly inspired from your code. Thanks for that, and of course I added you in my acknowledgments.
24 Mar 2010 Round with significant digits Rounds towards the nearest number with N significant digits. Author: François Beauducel

Thanks Oleg.
Yes, I will complete the "see also" function list in future updates.

1) you effectively need the "find" in Matlab versions < 7... and also single pipe for the OR test.
2) like you I have hesitated between "switch" and "feval". But the feval code is much shorter...

François.
22 Mar 2010 Round with significant digits Rounds towards the nearest number with N significant digits. Author: François Beauducel

Thanks Daniel for your time. I submitted an updated version that corrects the zero-value behaviour, and I added some options for the rounding method.
About the mlint messages, I kept my original syntax which is voluntarily backward compatible (with Matlab versions < 7).
