function() [3/5]

template<typename T >

cntr::function< T >::function	(	int	nt,
		int	size1,
		int	size2
	)

Initializes the function class for a non-square-matrix-valued function of time.

Purpose

Initializes the function class for a non-square-matrix valued function of time. nt = 0 leads to only one element (with time = -1), which is the value of function on the Matsubara axis (initial equilibirum)

Parameters

nt	Number of time steps
size1	Leading dimension of matrix
size2	Second dimension of matrix
