Thanks, Matteo!

The difference between this package and my previous 2006-2008 Color Space Converter is that colorspace is now implemented in C code. There are two advantages to this. First, colorspace now runs in MATLAB as a MEX function, which is noticeably more efficient than the previous M-code version. Second, colorspace can also be used from normal C and C++ programs---MATLAB is not required to use colorspace.

In case MEX is not an option, a pure M-code version of colorspace is also included (effectively an updated version of the previous colorspace).

Additionally, the sRGB definition of gamma-corrected RGB is now used, and two spaces have been added (HSI and CIE CAT02 LMS).

eric and x.d, I remember reading something like "the Image Processing Toolbox conversion is based on ICC profiles, and it uses a D65 to D50 Bradford adaptation transformation to the D50 white point." That may explain the differences?
