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

That was exactly what I needed

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.

This function allows me to place comment boxes on the plot and manually adjust them before inserting in presentation

Excellent work. Thanks

31 Oct 2014 xml_io_tools Read XML files into MATLAB struct and writes MATLAB data types to XML Author: Jaroslaw Tuszynski Leonardo

Thanks Jaroslaw, a very good tool!

I'm just having some troubles with newline (\n) serialization in text elements.

I'd like to write an xml like:
<root>
<p>This is a multiline
text.</p>
</root>

using

root.p = sprintf('This is a multiline\ntext.');

xml_write('multilinetext.xml', root)

but the var2str function implementation substitute all chars < 32 with ' '.
Keeping char(10) i.e. LF should allow this king of textual content.

Is this tool still under maintenance? A fix on this topic would be very useful.

Thanks in advance

I'm having trouble with the many rays, many faces option. Lets say I have 11 faces and 5 rays. What resizing of the inputs needs to be done? Do I need to repmat all arrays to be of size 55x3?

Based on what I can tell it can handle:
- one ray, many faces
- many rays, one face
- many rays, many faces (but # of faces = # of rays)

But I think I am just missing something here.

15 Oct 2014 Inscribed_Rectangle Computer vision functions to locate largest square or rectangle inscribed inside arbitrary shape Author: Jaroslaw Tuszynski Zoé

The code produces an incorrect result if the input is an entirely white image. Changing line 25 of FindLargestRectangles.m into "if max(I(:)) == 1" appears to solve this problem.

very good, but in my case, I get an OutOfMemoryError while dealing with 5.37m data. It seems too small
