Jordi -
With the FPL package in octave-forge you might accomplish what you want:

>> mesh.p=randn(2,10);
>> mesh.t = delaunay( mesh.p(1,:)', mesh.p(2,:)' )';
>> z = mesh.p(1,:)'.*mesh.p(2,:)';
>> FPL2pdesurf ( mesh, z );

FPL tries to emulate matlab's pdeplot (from the pdetool package)  
relying on opendx
