1.1.1.2. PyRates.pyrates.backend.fortran

1.1.1.2.1. pyrates.backend.fortran module

Fortran backend. Contains all fortran-based internal function definitions and links to fortran functions.

1.1.1.2.2. pyrates.backend.fortran.fortran_backend module

Wraps fortran such that it’s low-level functions can be used by PyRates to create and simulate a compute graph.

class pyrates.backend.fortran.fortran_backend.FortranBackend(ops: Dict[str, str] | None = None, imports: List[str] | None = None, **kwargs)

Bases: BaseBackend

add_code_line(code_str)

Add code line string to code.

add_var_update(lhs: ComputeVar, rhs: str, lhs_idx: str | None = None, rhs_shape: tuple | None = ())

break_line(code: str)

clear() → None

Removes all layers, variables and operations from graph. Deletes build directory.

Also removes the auto-07p artefacts generated by _generate_auto_files: every c.<scenario> file in the build dir, plus any pycobi-style s.<name> / b.<name> / d.<name> / .lab/.dat output files matching self._fname. Previously only c.ivp was removed, which orphaned all the other c.* files once we started generating multiple scenarios.

create_index_str(idx: str | int | tuple, separator: str = ',', apply: bool = True, **kwargs) → Tuple[str, dict]

static expr_to_str(expr: str, args: tuple)

generate_func(func_name: str, to_file: bool = True, func_args: tuple = (), state_vars: tuple = (), **kwargs)

generate_func_head(func_name: str, state_var: str = 'y', return_var: str = 'dy', func_args: list | None = None, add_hist_func: bool | None = None)

Generate the function header for the RHS file.

add_hist_func

Whether to include the hist callable in the generated function signature. If None (default), falls back to the backend’s add_hist_arg constructor flag — making that flag the single source of truth. Callers that already know whether the model is a DDE (e.g. ComputeGraph.to_func) pass the resolved bool explicitly and skip the fallback.

generate_func_tail(rhs_var: str | None = None)

linebreak_end = '&'

linebreak_start = '     & '

n1 = 62

n2 = 72

register_vars(variables: list)

1.1.1.2.3. pyrates.backend.fortran.fortran_funcs module

Contains fortran function definitions that may be used for PyRates model equations.

pyrates.backend.fortran.fortran_funcs.get_interp_def(idx: int, out_shape: tuple | str = '', dtype: str = 'real') → tuple

pyrates.backend.fortran.fortran_funcs.get_sigmoid_def(idx: int, out_shape: tuple | str = '', dtype: str = 'real') → tuple

pyrates.backend.fortran.fortran_funcs.get_sign_def(idx: int, out_shape: tuple | str = '', dtype: str = 'real') → tuple
