what is the recommended way to check, during the preprocessing phase, if

I would suggest EIGEN_WORLD_VERSION (has been defined at least since 2.0.0) But why do you need to check that? Shouldn't usually just including it be better?

Thanks Christoph!

I'm writing an MD5sum class for debugging. With this I can print the md5sum of an object to easily compare two versions of programs which should produce identical objects. Since I don't want to include Eigen for any program which uses this class, I define the specialized templates for Eigen Matrix or Array objects only if the Eigen header
has been included already.
