POD is really at the end of the day not much more than computing (in some clever way) the SVD of a data matrix. For POD to be really really useful, one needs to build efficient projection onto the POD basis. We should keep this in mind when going down this road!

DEIM is a remedy to this problem. So it makes sense to do POD in conjunction with #12 .
