herm_matrix_timestep_view() [6/7]

template<typename T >

cntr::herm_matrix_timestep_view< T >::herm_matrix_timestep_view	(	int	tstp,
		herm_matrix_timestep< T > &	g,
		bool	check_assert = true
	)

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. First argument tstp is redundant, but present due to the safety [and historical] reason. Works for scalar or square-matrix contour objects

Parameters

tstp	Index of time
g	The herm_matrix_timestep according to which the class should be initialized
check_assert	Flag: true or false. Includes assertions
