19 Sep 2014 Triangle/Ray Intersection Fast vectorized triangle/ray intersection algorithm Author: Jaroslaw Tuszynski Jaroslaw Tuszynski

Reply to Nick: In many rays and many triangle case you still test for intersection of prearranged pairs and the return value informs you which ray/triangle pair intersected

Reply to Bruce:
I had the same problem lately after upgrading to 64-bit computer and installing 64-bit MATLAB. Apparently my MS Office was 32-bit and neither this toolbox nor MATLAB Database Toolbox was able to work with it. I solved the problem by uninstalling 32-bit office and reinstalling 64-bit version.

Idea is great and it works for some plots. I had issues with plots being incorrectly resized that required code changes. I also had some blots for which this function placed tick labels inside the plot area. So it needs more debugging and possibly a tutorial page with examples.

06 Oct 2012 Triangle/Ray Intersection Fast vectorized triangle/ray intersection algorithm Author: Jaroslaw Tuszynski Jaroslaw Tuszynski

Re to Anton Semechko: This is a low level function which can be called with one ray and many faces, many faces and one ray or many faces and rays. It is quite simple to apply repmat function to the inputs.

Very useful function. i found it especially useful for creating images for PowerPoint presentations which were small enough to be send by email.

This function does not seem to work for me. The output mesh does not resemble much the input mesh. I was expecting that all the original points would be preserved, but that is not the case.

Reply to Pete:
I was using this script to add a lot (~60k) of records to access DB, and use access as temporary memory storage to get some MATLAB codes to run on machined with 2GB or RAM. I did not notice any "extreme" slowness, but that might be relative.

The error you see might be due to MS access not supporting multiple queries.

You can not call it ENVI reader and only support small fraction of cases file format supports.

06 May 2011 xml_io_tools Read XML files into MATLAB struct and writes MATLAB data types to XML Author: Jaroslaw Tuszynski Jaroslaw Tuszynski

Reply to vaiadubai:
Creation of xml text is done within MATLAB xmlwrite or more precisely within java code called by xmlwrite. xmlwrite does not provide any parameters to customize the output, and java probably does not either. one possible solution is to open resulting file as text and perform global replace of 2 spaces with one.

16 Sep 2010 xml_io_tools Read XML files into MATLAB struct and writes MATLAB data types to XML Author: Jaroslaw Tuszynski Jaroslaw Tuszynski

Reply to Christoph:
You can always perform your own matrix to string conversion, I am doing conversion equivalent to
X.linear.tensor.real=mat2str(X.linear.tensor.real);
xml_write('test.xml',X);
but you can replace the first line and do some other conversion prior to writing. One thing you might not be able to do is to put a new line on the end of each row. It seems like MATLAB's xmlwrite (called by my xml_write) strips those.

Reply to Peter Cotton:
Current library was never tested with sparse matrices, and I am actually surprised at its behavior, which I kind of like for most part. I will modify it so xml_read returns a sparse matrix.

Reply to Bree:

Try reading with
Pref.Str2Num = 'always';
MyTree1=xml_read('test.xml',Pref);

Default Str2Num preference is 'smart' which does not try to convert strings with more than 10k characters. Occasionally the strings in XML can be VERY large, for example when you have Base64 encoded images in the file. In such cases regexp code I am using can be very slow.

Reply to 12 Jan 2010 message by Michael Glanznig: I am trying to be very cautious with str2num since it is based on matlab eval function and sometimes gives very unexpected results and I am using it to test is the string can be changed to a number. Try for example str2num('sphere').

File emd.m relays on function linprog which does not seems to be neither standard MATLAB function and is not included in the package. Is it part of some MATLAB toolbox or is it available in this file exchange repository?

Reply to Val Schmidt Comments:

By default xml_read is configured for most common use. If you need performance, DOMnode2struct can be sometimes significantly speeded up if you use Pref.Str2Num='never' and/or trim your output by changing Pref.ReadAttr, Pref.ReadSpec and Pref.NumLevels.
