示例1: _new_comp

# 或者: from sage.tensor.modules.free_module_tensor.FreeModuleTensor import _new_comp [as 别名]
def _new_comp(self, basis):
r"""
Create some (uninitialized) components of ``self`` in a given basis.
INPUT:
- ``basis`` -- basis of the free module on which ``self`` is defined
OUTPUT:
- an instance of :class:`~sage.tensor.modules.comp.Components` or,
if ``self`` is the identity, of the subclass
:class:`~sage.tensor.modules.comp.KroneckerDelta`
EXAMPLES::
sage: M = FiniteRankFreeModule(ZZ, 3, name='M')
sage: e = M.basis('e')
sage: a = M.automorphism()
sage: a._new_comp(e)
2-indices components w.r.t. Basis (e_0,e_1,e_2) on the Rank-3 free
module M over the Integer Ring
sage: id = M.identity_map()
sage: id._new_comp(e)
Kronecker delta of size 3x3
sage: type(id._new_comp(e))
<class 'sage.tensor.modules.comp.KroneckerDelta'>
