triqs_dft_tools.block_structure.BlockStructure.convert_gf
- BlockStructure.convert_gf(G, G_struct=None, ish_from=0, ish_to=None, show_warnings=True, G_out=None, space_from='solver', space_to='solver', ish=None, **kwargs)[source]
Convert BlockGf from its structure to this structure.
Warning
Elements that are zero in the new structure due to the new block structure will be just ignored, thus approximated to zero.
- Parameters:
- GBlockGf
the Gf that should be converted
- G_structBlockStructure or str
the structure of that G or None (then, this structure is used)
- ish_fromint
shell index of the input structure
- ish_toint
shell index of the output structure; if None (the default), it is the same as ish_from
- show_warningsbool or float
whether to show warnings when elements of the Green’s function get thrown away if float, set the threshold for the magnitude of an element about to be thrown away to trigger a warning (default: 1.e-10)
- G_outBlockGf
the output Green’s function (if not given, a new one is created)
- space_from‘solver’ or ‘sumk’
whether the Green’s function
Gcorresponds to the solver or sumk structure ofG_struct- space_to‘solver’ or ‘sumk’
whether the output Green’s function should be according to the solver of sumk structure of this structure
- **kwargs
options passed to the constructor for the new Gf
