Which code are you refeering to exactly?

In the code I know, you have to apply it yourself. However, this code is
still fairly barebones, and will need more work, in particular to define
good APIs. This will happen when we merge in the manifold module (give it
a month).

The code for diffusion maps is indeed fairly short, but in the scikit we
play all the tricks we can to be numerically efficient (and they are not
always trivial).
