Advice on resurrecting a project created back when when Matlab had a c++ maths library

Hi all,

I'm trying to resurrect an old c++ project that used mwArrays as its "matrix class" for computations, e.g.

mwArray A = ones(1,3);
mwArray B = eye(3);
mwArray C = A * B;

which appears to have been phased out. It puts / takes data to / from the Matlab workspace so I can't use just old versions of the mwArray libraries.

I'm not sure what approach to take to get it up and running with the least pain. Any advice would be greatly appreciated!
