Laplacian
(dims, dirs=(0, 1), weights=(1, 1), sampling=(1, 1), compute=(False, False), chunks=(None, None), todask=(False, False), dtype='float64')[source]¶ Laplacian.
Apply second-order centered Laplacian operator to a multi-dimensional array (at least 2 dimensions are required)
Parameters: - dims :
tuple
Number of samples for each dimension.
- dirs :
tuple
, optional Directions along which laplacian is applied.
- weights :
tuple
, optional Weight to apply to each direction (real laplacian operator if
weights=[1,1]
)- sampling :
tuple
, optional Sampling steps for each direction
- compute :
tuple
, optional Compute the outcome of forward and adjoint or simply define the graph and return a
dask.array.array
- chunks :
tuple
, optional Chunk size for model and data. If provided it will rechunk the model before applying the forward pass and the data before applying the adjoint pass
- todask :
tuple
, optional Apply
dask.array.from_array
to model and data before applying forward and adjoint respectively- dtype :
str
, optional Type of elements in input array.
Returns: - l2op :
pylops.LinearOperator
Laplacian linear operator
