find_min_signature

odl.ufunc_ops.ufunc_ops.find_min_signature(ufunc, dtypes_in)

Determine the minimum matching ufunc signature for given dtypes.

Parameters

ufuncstr or numpy.ufunc

Ufunc whose signatures are to be considered.

dtypes_in :

Sequence of objects specifying input dtypes. Its length must match the number of inputs of ufunc, and its entries must be understood by numpy.dtype.

Returns

signaturestr

Minimum matching ufunc signature, see, e.g., np.add.types for examples.

Raises

TypeError

If no valid signature is found.
