Hi,

Manual works perfect. I have several programs that send
a 2d arrays to Mathematica, of course I have no "objects", and
I don't know how your vector/matrix class is defined but

MLPutFunction(stdlink,"Partition",2);
  MLPutRealList(stdlink,yourArray,n*m);
  MLPutInteger(stdlink,n);

will work with a one-dimensional adress scheme
and

MLPutFunction(stdlink,"List",n);
for(i=0; i<n; i++)
  MLPutRealList(stdlink,yourRows[i],m);

works for a array of pointers to rows.

Regards
  Jens
