signbit

odl.ufunc_ops.ufunc_ops.signbit(domain=RealNumbers())

Returns element-wise True where signbit is set (less than zero).

numpy.signbit

Notes

This creates a Operator/Functional that applies a ufunc pointwise.

Examples

Create operator that acts pointwise on a TensorSpace

>>> space = odl.rn(3)
>>> op = odl.ufunc_ops.signbit(space)

Create functional with domain/range as real numbers:

>>> func = odl.ufunc_ops.signbit()
