Table 2
Selection of instance methods of the NIFTy field class.
| Method name | Description |
|
|
|
| cast_domain | alters the field’s domain without altering the field values or the codomain. |
| conjugate | complex conjugates the field values. |
| dot | applies the scalar product between two fields, returns a scalar. |
| tensor_dot | applies a tensor product between two fields, returns a field defined in the product space. |
| pseudo_dot | applies a scalar product between two fields on a certain subspace of a product space, returns a |
| scalar or a field, depending on the subspace. | |
| dim | returns the dimensionality of the field. |
| norm | returns the L2-norm of the field. |
| plot | draws a figure illustrating the field. |
| set_target | alters the field’s codomain without altering the domain or the field values. |
| set_val | alters the field values without altering the domain or codomain. |
| smooth | smoothes the field values in position space by convolution with a Gaussian kernel. |
| transform | applies a transformation from the field’s domain to some codomain. |
| weight | multiplies the field with the grid’s volume factors (to a given power). |
