template<typename T >

void cntr::herm_matrix< T >::read_from_hdf5

(

hid_t

group_id

)

Reads herm_matrix from a given HDF5 group handle.

Purpose

Reads the herm_matrix, including the matrix size, number of points on real and imaginary axis and fermionic/bosonic character, from a given HDF5 group handle.

Parameters

group_id

[hid_t] The HDF5 group handle from which the herm_matrix is read.
