DRAFT : to be tested further...
- update gf<imfreq>
- write a specific mesh for matsubara frequencies
- now the cast series is :
mesh_pt --> matsubara_freq --> complex<double>
- matsubara_freq is just the matsubara frequency
- arithmetic of the mesh_pt casted to matsubara_freq
- arithmetic of matsubara_freq is casted to complex, except + and -,
which are kept as matsubara_freq.
- evaluator now accept : int, mesh_pt, and matsubara_freq
for matsubara_freq : for negative omega, use conjugation
for omega outside windows, evaluate the tail on omega.
- as a result : g( om - nu) where om, nu are 2 meshes points,
is the extrapolation outside the grid if necessary.
- updated tests
- added evaluation for tail.
- a(1,ellipsis()) for a an array<T,1> e.g.,
was not compiling.
- also added const_iterator for range to allow simple code :
for (auto i : range {3,6}) ....-> i = 3,4,5 as in python
- clef : fix a little bug in storage when evaluating
(was using the wrong trait to deduce storage type).
- gf : block :
- added reinterpret_scalar_valued_gf_as_matrix_valued
for block function
- cleaned make_block_gf_view_from_vector
- added make_block_gf_view_from_vectormake_block_gf_view_from_vector_of_cython_proxy
and changed the cython accordingly because it requires a slightly different syntax.
- updated tests
- gf : cleaned some template.
- lazy_fourier and co --> fourier
- ex fourier --> make_gf_from_fourier to make a new gf
- = fourier (g) works only iif lhs is a view, like scalar.
- updated python (commented fourier method).
- was a bug workaround. Should be ok, but
reason of previous fix unclear. Suspicious...
- necessary to remove this :
- it is useless normally.
- it prevent the evaluator to work for scalar valued gf
- Make more general constructors for the gf.
gf( mesh, target_shape_t)
- remove the old make_gf for the basic gf.
- 2 var non generic gf removed.
- clean evaluator
- add tensor_valued
- add a simple vertex test.
- clean specialisation
- Fix bug introduced in 1906dc3
- forgot to resize the gf in new version of operator =
- Fix make_singularity in gf.hpp
- clean resize in operator =
- update h5 read/write for block gf
- changed a bit the general trait to save *all* the gf.
- allows a more general specialization, then a correct for blocks
- NOT FINISHED : need to save the block indice for python.
How to reread ?
Currently it read the blocks names and reconstitute the mesh from it.
Is it sufficient ?
- clean block constructors
- block constructors simplest possible : an int for the number of blocks
- rest in free factories.
- fixed the generic constructor from GfType for the regular type :
only enable iif GfType is ImmutableGreenFunction
- multivar. fix linear index in C, and h5 format
- linear index now correctly flatten in C mode
(was in fortran mode), using a simple reverse of the tuple in the folding.
- fix the h5 read write of the multivar fonctions
in order to write an array on dimension # variables + dim_target
i.e. without flattening the indices of the meshes.
Easier for later data analysis, e.g. in Python.
- merge matrix/tensor_valued. improve factories
- matrix_valued now = tensor_valued<2>
(simplifies generic code for h5).
- factories_one_var -> factories : this is the generic case ...
only a few specialization, code is simpler.
- clef expression call with rvalue for *this
- generalize matrix_proxy to tensor and clean
- clean exception catch in tests
- exception catching catch in need in test
because the silly OS X does not print anything, just "exception occurred".
Very convenient for the developer...
- BUT, one MUST add return 1, or the make test will *pass* !!
- --> systematically replace the catch by a macro TRIQS_CATCH_AND_ABORT
which return a non zero error code.
- exception : curry_and_fourier which does not work at this stage
(mesh incompatible).
- gf: clean draft of gf 2 times
- comment the python interface for the moment.
- rm useless tests
- the arithmetics of the gf mesh_points :
the forwarding of the second argument was missing,
leading to subtle bugs e.g. in (in matrix case) :
deltaw(iom_) << iom_ * gw.singularity()(-1) + gw.singularity()(0) - gw(iom_);
because the partial evaluation of the expression introduced a dangling const matrix_view &
instead of moving the temporary matrix_view into the final matrix expression template.
- clean array, matrix, vector expression template
they take const & of objects, or move && objects
no more views. -> C++11 modernisation
- Fix a bug in array resize : it was resetting the indexmap
to C memory layout e.g. for a fortran array
- Fix a bug in read h5 array when not in C order
(forgot an else, the array was read twice).
- When evaluation produces temporaries in intermediate
steps, they were capture by ref, not properly forwarded.
This results in bugs in more complex cases,
like evaluation of objects returning new arrays expression template.
(preparation for next commit).
This reverts the part of the commit 1906dc30a5
which introduced modifications in the expr templates of the Green's
functions. The commit had introduced some bugs and this revert
removes them (the expr templates will be taken care of fully in later
commits). This is a temporary fix for issues #18 and #25.
