05 Dec 2013 MTIMESX - Fast Matrix Multiply with Multi-Dimensional Support Beats MATLAB 300% - 400% in some cases ... really! Author: James Tursa

Works well for me on Linux.

If it can helps, I have installed the library libblas.so in my home following the version "shared library" of this page: http://gcc.gnu.org/wiki/GfortranBuild

Then I have compiled the mex file with the command return by the mtimesx routine when the automatic installation failed:
blas_lib = 'the_actual_path_and_name_of_your_systems_BLAS_library';

Gained a factor 2 in speed for my 3D matrices multiplications, and a clearer matlab code :)

15 Nov 2013 Fast 2-dimensional interpolation Provides a 5x-50x speedup over interp2 Author: Nathaniel Brahms

On R2012a, for very small interpolations (2x2 matrices interpolated in 1 point), speed up by a factor 10!

31 Jul 2013 Inpaint over missing data in 1-D, 2-D, 3-D,... N-D arrays Y = INPAINTN(X) computes the missing data in the N-D array X. Author: Damien Garcia

Very good submission. I was working on my own version of this problem when a google research send me here and save me several hours of work. Thanks!

22 Mar 2013 Copy / Clone method for handle and hgsetget class Enable deep copying of child objects of classes handle or hgsetget Author: Sebastian Hölz

The problem is this class cannot handle the copy of protected/private properties defined by the classes which derive from it. Thus we need to declare public all the properties of the children classes and so forget encapsulation...

It is not a criticism, there is no way to reach private and protected properties of a subclass from its superclass, so you cannot do better :)
