-> code was previously assuming mesh with only positive, fermionic matsubara freqs
-> changed wn_min to n_min (was misleading, since it was an index, not a frequency) / same for <-> max
-> changed doc accordingly
-> Previously, calculation was implicitly assuming a mesh with only positive matsubara frequencies.
-> Added corresponding test
-> Also added test of density calculation with or without correct tail.
- add c14 include
- the C++14 is lot more readable (due to generic lambda).
- for mesh/product.hpp -> now 2 versions (C++14 and C++11 for temporary
backward compatibility).
Pb :
M() = rhs; // rhs of type RHS
Currenlty does :
M(i,j) = (i==j ? rhs : RHS{})
Changed to
M(i,j) = (i==j ? rhs : RHS{0*rhs})
If RHS is a double, int ... Same result.
If RHS is a matrix, gf, currently the offdiag elements
are default constructed (i.e. of 0 size !).
Which can break operations later (matrix<matrix<double>>)
After change : all elements have the same size !
- use alias
- rename a few things, simplify
- some clang format
- add eval to ref wrapper
- correct evaluator general (return const &, no copy)
- correct declaration order of struct and operator OP
- forgot to correct the value_type of matrix_expr, and vector_expr
as was done long ago for arrays...
- also added cases for arrays until dim 10
- TODO : replace this trait in arrays with a tuple tools for any dim..
not urgent.
- for pieces that need to be precomputed for several
measures.
- put them under shared_ptr, and register then with add_measure_aux.
- they must be callable, as void ().
- TODO : add this in the doc when tested
- the condition p%2 ==1 was wrong if p<0 (never true!)
- added corresponding test (gf_notail)
Conflicts:
triqs/gfs/imtime.hpp
Fixed by O.P. : already fixed in Laura's pull request ...
- gf<cartesian_product<imfreq,imfreq>> was not correct
when out bounds. Fixed evaluator.
- tensor_proxy : fix the trait for algebra which was incorrect.
- TODO: clean code (repetition, put in mesh some windowing).
- there was a confusion in gf imfreq, in the new case
where freq can be <0 (non real gf, or for product gf).
- index: is the matsubara n, as in the struct matsubara_freq
index can be >0 or <0
- linear_index : is the shift from the 0. It is always >0.
Fixed function to compute it.
- Also changed the construction of mesh_point in the generic iterator.
Before, was constructed with a mesh point of index 0
Now, added a new constructor on mesh_point_t, just taking the mesh
which construct the *first* mesh_point.
Fixed linear, discrete, product accordingly.
Added to the documentation of the concepts of gf.
- little details : code cleaning, clang formatting, along
with documentation writing for c++ gf.
- separated the mesh in small class for better doc.
- work on documentation : reorganize specialisation, ...
std::conj returns a complex according to std.
On gcc, we need to define it (bug?) but on clang libc++
it is an error.
-> one test is still failing : to be decided later
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.
