[eigen] Deducing associated type in eigen3

[Brook Milligan <brook@xxxxxxxx>]

I am trying to discover if Eigen provides any meta functions for deducing types associated with the main Eigen types, e.g., arrays, matrices, etc.  For example, is there any way to determine what the scalar type associated with a matrix is?

I am not seeing any way to do this in the documentation, but perhaps I just have not found it yet.  It is certainly not highlighted.

Thanks for your help.

Cheers,
Brook
