06 Jun 2011 Find Euler Angles An interactive demo for learning and visualizing 3D coordinate transformations and Euler angles. Author: Dmitry Savransky

This submission uses the 'unused argument syntax' introduced in R2009b. (see: http://blogs.mathworks.com/steve/2010/01/11/about-the-unused-argument-syntax-in-r2009b/ ) Users of earlier versions will most likely encounter errors. You can fix these quite easily by replacing the tildes in various subfunction syntax declarations with dummy variables. I apologize to all pre-R2009b users for the inconvenience.
15 Jun 2010 Mathematica Symbolic Toolbox for MATLAB--Version 2.0 A symbolic toolbox for MATLAB based on Mathematica. Author: Ben Barrowes

As usual from this author, a great addition to MATLAB. Quick note for those compiling on OS X - make sure you edit math.c line 227 as suggested in the comments below it, but don't worry about setting the library path. Your mex line should be something like:
mex -I/Applications/Mathematica.app/SystemFiles/Links/MathLink/DeveloperKit/CompilerAdditions/ -L/Applications/Mathematica.app/SystemFiles/Links/MathLink/DeveloperKit/CompilerAdditions/ -lMLi3 math.c

12 Oct 2009 Multiple Precision Toolbox for MATLAB This toolbox defines a new mp class allowing multiple precision objects in MATLAB. Author: Ben Barrowes

Absolutely fantastic. Exactly what I needed - many thanks. Quick note for anyone installing on RHEL5. The default rpms that may be pre-installed for GMP don't seem to work when it comes time to compile the c files. However, if you get rid of these and compile GMP and MPFR from source, everything works great.

30 Nov 2012 UDFactor Performs the U-D factorization of a symmetric matrix. Author: Dmitry Savransky sun

very usefule
14 Nov 2012 Find Euler Angles An interactive demo for learning and visualizing 3D coordinate transformations and Euler angles. Author: Dmitry Savransky John

Based on earlier comment on your other program for euler angles, it would be nice if there was a text box to type in angles
14 Nov 2012 animEuler Animate sets of Euler rotations using arbitrary Euler angles and rotation order. Author: Dmitry Savransky John

Hi Dmitry, I would like to continue doing a second (or even multiple) euler angle rotations based on / after the first euler angle rotation, on the same pre-existing figure. Then, to retrieve the resultant 'net' data. Using your helper function rot3daxes, this seems almost doable. Any assistance is appreciated

06 Apr 2012 Lomb (Lomb-Scargle) Periodogram Computes the Lomb normalized periodogram (spectral power as a function of frequency). Author: Dmitry Savransky Yoshiki
