Some Extensions for Eigen3

Summary

This repository contains some extensions for Eigen3.

Features (my memo)

header only
c++11-like interface (random,initializer_list)
Eigen-like interface (some solver classes)
no json interface for Eigen (, which is separated to other repositories)
no dependence on my "cmpt/util.hpp"

Contents

c++11-like random distribution for Vector, Matrix, Tensor in Eigen3
Lanczos method
Arnoldi method
multi-dimensional indices interpreter
SVD(Singular Values Decomposition) for Tensor
BlockTensor (tensor class for block sparse tensor)
numpy-like einsum (under construction)
etc...

Dependences

c++11

for some functions

Eigen3

For #include "Eigen/...". The include path must contains unsupported/CXX11 to use Tensor classes.
