triqs.gf.block2_gf.Block2Gf

class triqs.gf.block2_gf.Block2Gf(name_list1, name_list2, block_list, **kwargs)[source]: Generic Green’s Function by two-index Block.

Methods

`__init__`(name_list1, name_list2, block_list, ...)	Block2Gf(name_list1, name_list2, block_list, make_copies = False, name = 'G2')
`copy`(*args)	Returns a (deep) copy of self (i.e. new independent Blocks initialised with self).
`copy_from`(G2)	Copy the Green's function from G2: G2 MUST have the same structure!
`copy_selected_blocks`(selected_blocks1, ...)	Returns a COPY of the selected blocks of self, in the same order as self.
`view_selected_blocks`(selected_blocks1, ...)	Returns a VIEW of the selected blocks of self, in the same order as self.
`zero`()

Attributes

`all_indices`	An Iterator on Block2Gf indices and indices of the blocks of the form: block_index1,block_index2,n1,n2, where n1,n2 are indices of the block
`imag`	A Gf with only the imag part of data.
`indices`	A generator of the block indices
`indices1`	A generator of the first block indices
`indices2`	A generator of the second block indices
`n_blocks`	Number of blocks
`real`	A Gf with only the real part of data.
