cutcutcodec.core.compilation.sympy_to_torch.printer_atom.c_abs(out: Symbol, indexing: defaultdict[Symbol, str], c_type: str, arg: Atom) → tuple[set[str], set[Symbol], list[str]][source]¶

C abs operation.

Examples¶

>>> from sympy.abc import x
>>> from sympy.functions.elementary.complexes import Abs
>>> import numpy as np
>>> from cutcutcodec.core.compilation.sympy_to_torch.lambdify import _lambdify_c
>>> from cutcutcodec.core.compilation.sympy_to_torch.printer import _print_atomic, _printer
>>> func = _lambdify_c(_printer([(x, Abs(x))], {}, {x}))
>>> func(np.array([np.nan, -np.inf, -2., 2., np.inf]))
array([nan, inf,  2.,  2., inf])
>>> func(np.array([3+4j, -3+4j, 3-4j, -3-4j]))
array([5.+0.j, 5.+0.j, 5.+0.j, 5.+0.j])
