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.

06 Aug 2013 Rotate X-axis tick labels Rotate x-tick labels to any angle, preserving font settings and coping with resize, zoom, pan etc Author: Ben Tordoff

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

22 Jul 2014 xml_io_tools Read XML files into MATLAB struct and writes MATLAB data types to XML Author: Jaroslaw Tuszynski Yodit

hi I am new to matlab, I was trying to chnage an xml file(which is too large it looks like this:
Result_Matrix =

[ 46686]
[ 4]
'f'
[1x2987899 char ]
[1x1 struct]

but I am interested in having the data [1x2987899 char ] part in (4x46686)matrix format. Can someone please explain how I can do that. Thank you in advance.

24 Mar 2014 Triangle/Ray Intersection Fast vectorized triangle/ray intersection algorithm Author: Jaroslaw Tuszynski Nick

Very useful but when considering many rays and many triangles is there a way to find which ray has intersected which triangle?

Beautiful work!
Why when I run the PhotonAttenuation_Tutorial.m directly, it will display the error information as:
"
Error: File: PhotonAttenuation.m Line: 192 Column: 3
"mu" previously appeared to be used as a function or command, conflicting with its use here as the name of a variable.
A possible cause of this error is that you forgot to initialize the
variable, or you have initialized it implicitly using load or eval.

Error in test_YZ (line 10)
mac = PhotonAttenuation(Z, E, 'mac');
"
