I’m not sure that the intent for the hash function was actually what is
currently in the code, but it’s not worth improving this given that we want to
get rid of Dynare++ and the performance impact is probably negligible.
They don’t bring any added value, and break compilation in C++20 mode (because
they are then of type “const char8_t *” which is distinct from “const char *”).
It is now supported by the MATLAB editor (as of R2022a).
The old ASCII notation is left in some files that we copy as-is from other
sources (e.g. in the contrib/ and m4/ subdirectories).
The particles submodule is not updated at this point, because it is in an
inconsistent state.

Note that the unitary test in lyapunov_solver.m that checks sparse matrix input
had to be removed. Previously, this test was passing by chance (because the
sparse test matrices had actually no zero element, hence the internal double
float storage was the same as in the dense case). Now it consistently fails
with the additional checks in disclyap_fast MEX.
This option could crash or give wrong results.
Bug introduced in 6d99b6d120.
The Vector(Vector &) and Vector(const Vector &) constructors are not
equivalent.
Closes: #1804
Partially addresses issue #1680:
- unconditional welfare resorts to dynare++ simulation tools, which shall be updated very soon
TO DO:
- implement a function computing kth-order approximation of simulated moments of y
It applies the approximated policy function to a set of particles, using
Dynare++ routines.
There is support for parallelization, using Dynare++ multithreading
model (itself based on C++11 threads; we don’t use OpenMP because it is
incompatible with MKL). For the time being, default to a single thread. This
should be later refined through empirical testing.
In particular, if either MATLAB or Octave is missing, one needs to pass either
--disable-matlab or --disable-octave.
Moreover, several new configure flags have been introduced for disabling some
components:
--disable-doc
--disable-dynare++
--disable-mex-dynare++
--disable-mex-ms-sbvar
--disable-mex-kalman-steady-state
Previously, if Blanchard-Kahn conditions were not satisfied, there was the
possibility an exception about NaN/Inf values in gy/gu was raised *before* the
exception about BK itself, leading to a confusing message. This commits moves
the test for BK before the test for NaN/Inf in gy/gu.
Closes: #674
— Ondra Kamenik has agreed to the relicensing of utils and parser modules to
GPL
— add DynareTeam’s copyright, since we have made a lot of modifications
— add proper copyright notices in all files
