Calling Matlab function from Postgres

I'm trying to call MATLAB functions from PostgreSQL. I was trying to use Joshua Kaplan's java MATLAB control. I install my jar file which in turn calls MATLAB to run my algorithm, but get the error message "ERROR: java.lang.NoClassDefFoundError: matlabcontrol/RemoteMatlabProxyFactory" when I call the java function. I saw where DerTech LLC developed a MATLAB interface for PostgreSQL, but their web site seems to be gone. Does anyone either have an idea of how to solve my error or have a copy of the code that DerTech developed for the interface?

Thank you,
Susan
