herm_matrix_timestep_view() [3/7]

template<typename T >

cntr::herm_matrix_timestep_view< T >::herm_matrix_timestep_view

(

herm_matrix_timestep< T > &

g

)

Initializes the herm_matrix_timestep_view class with the same layout as a given herm_matrix_timestep g.

Purpose

Initializes and copy the herm_matrix_timestep_view class from the herm_matrix_timestep with the same number of time steps nt, number of points on the imaginary branch ntau, matrix rank size1 and bosonic/fermionic symmetry sig. No data, only pointers are copied. Works for scalar or square-matrix contour objects

Parameters

g	The herm_matrix_timestep according to which the class should be initialized
