The Matlab code for accessing MySQL databases comes from Robert Almgren at University of Toronto. The source code has been copied to the matlab directory.
The source code has been compiled on a Mac OS 10.2 platform. To use the program copy the files mysql.m and mysql.mexmac from the matlab directory to a directory that is included in your Matlab search path. Type help mysql at the Matlab command prompt to get a description of the function.
See the instructions on the Robert Almgren page.
