Detailed Description

Container of Field-type object.

This class defines field-type quantity which has three size parameters, Nin: on-site degree of freedom, Nvol: site d.o.f, Nex: extra d.o.f. The detailed structure of these degrees of freedom is not defined in this class but in subclasses. Expression template was implemented by J.Noaki. [28 Dec 2011 H.Matsufuru]

add dot_and_nomr2, dotc_and_norm2 [30 Sep 2019 I.Kanamori] change myindex from int to size_t [ 6 Jan 2020 I.Kanamori]
