field_inverse_tikhonov

hcipy.field.field_inverse_tikhonov(f, rcond=1e-15)

Invert a tensor field of order 2 using Tikhonov regularization.

Parameters

fField or ndarray

The tensor field for which to calculate the inverses. The tensor order of this Field has to be 2. If it is not a field, a normal inverse with Tikhonov regularization will be returned.

rcondscalar

The relative regularization parameter to use for the inversions.

Returns

Field or ndarray

The resulting Field with tensor order 2.

Raises

ValueError

If the tensor order of field f is not 2.
