Unfortunately it is not possible to enable it for all supported Octave
versions (which would have allowed us to remove the old codepath), because of
this bug: https://savannah.gnu.org/bugs/?64687
The statement “implicit none” forbids implicit typing of variables, but not
implicit procedure declaration. The new “implicit none (type, external)” syntax
forbids both, and is thus safer.
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.
- Creates the library `libkordersim` with all the relevant Fortran routines to `folded_to_unfolded_dr` and `local_state_space_iteration_fortran`
- Implements `folded_to_unfolded_dr`, which converts folded decision rule matrices to their unfolded counterparts
This can make a difference when the return value of those function is directly
passed to a BLAS/LAPACK function.
On the other hand, if the return value is first stored in a pointer variable,
then it seems necessary to explicitly say that this pointer is also contiguous.
— add interface for more functions (cell, logical, struct)
— add new mexPrintf wrapper that trims and prints a newline
— functions that take indices of type mwIndex now 1-based indices
— improve the wrapper for mxArrayToString so that it returns a character scalar
