===================================================
|

This is a specialisation of :ref:`gf_and_view` for imaginary Matsubara frequencies.

Domain & mesh

Interpolation method
|
|
---------------------
|
|
|
|
Linear interpolation on the mesh.
|
|
|
|
Data storage
|
|
---------------
|
|
|
|
* `data_t` : 3d array (C ordered) of complex<double>.
|
|
|
|
* g.data()(i, range(), range()) is the value of g for the i-th point of the mesh.
|

|
|
HDF5 storage convention
|
|
---------------------------
|
|
|
|
h5 tag : `ReFreq`
|

Examples

|
---------
|
|
|
|
.. compileblock::
|

#include <triqs/gfs/refreq.hpp>

|
using namespace triqs::gfs;
|

|
|
int main() {
|
|
double wmin=0, wmax=10; // Frequencies interval
|
|
auto n_freq=100; // Number of points
|
|
|
|
// We want a 2x2 matrix valued function on this mesh...
|
|
auto g = gf<refreq> { {wmin, wmax, n_freq}, {2,2} };
