05 Aug 2009 txt2mat fast and versatile ascii data import capable of handling large text files Author: Andres

This seems like a terrifically useful tool.

One feature request. In addition to being able to specify characters that, if found in a line, mark the line for omission, it would be nice to be able to instead skip everything by default and specify characters of lines that are to be included.

Suppose, for example, you want to parse a log file. You'll want to extract all the log entries of a particular type. Rather than having to specify every other type of entry for omission, it'd be nice to be able to specify just the ones you want.

Thanks,
Val
21 Jun 2009 xml_io_tools Read XML files into MATLAB struct and writes MATLAB data types to XML Author: Jaroslaw Tuszynski

This package works well for us - reading xml that fails under other xml packages.

However it is EXTREMELY slow (for me).

In parsing a 976K xml file with a parent function that calls xml_read(), I find in profiling that "xml_read>DOMnode2struct" consumes 206 seconds of the total 210.

It appears that the process of unwrapping the results of the DOM object into the matlab structure is what kills it. Oddly, my cpu is rarely maxed out, which seems to indicate some memory management bottleneck.

Is there any chance this is fixable?

10 Feb 2009 Cone-plane intersection Compute the intersection of a cone and a plane, where the result is represented as an ellipse Author: Sylvain Calinon

I want to comment on my own comment The author of this package emailed me directly, pointing out that I had failed to normalize the coneDir vector.

SO PLEASE DISREGARD MY MESSAGE ABOVE.

The error was mine!

14 May 2009 get_google_map Retrieve a google map from the command line using the Static Google Maps API. Author: Val Schmidt us

once the user has set the environment

- get the KEY
- get DEG2UTM

it works quite well for most of the prop/val combinations

two thoughts

no need to FLIPUD(M) in the function... otherwise, users have to flip it back for

     imagesc(XX,YY,flipud(M));
     colormap(Mcolor);
     axis image;

which seems a faster/better way to display the map compared to the proposed SURF(...)

the props should be case-insensitive...
