resize()

template<typename T >

void cntr::herm_matrix_timestep< T >::resize	(	int	tstp,
		int	ntau,
		int	size1
	)

Resizes herm_matrix_timestep object with respect to the number of points on the Matsubara branch and the matrix size at a given timestep .

Purpose

Resizes herm_matrix_timestep class with respect to number of points on the Matsubara branch ntau and the matrix size size1 at a given timestep tstp. Works for a square matrices.

Parameters

tstp	time steps
ntau	number of points on Matsubara branch
size1	size of the square matrix
