field_inverse_truncated

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

Invert a tensor field of order 2 using mode truncation.

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 truncated inverse will be returned.

rcondscalar

The relative condition number of the highest-order mode that must be used for inversion.

Returns

Field or ndarray

The resulting Field with tensor order 2.

Raises

ValueError

If the tensor order of field f is not 2.
