pylops_distributed.Transpose

class pylops_distributed.Transpose(dims, axes, compute=(False, False), todask=(False, False), dtype='float64')[source]

Transpose operator.

Transpose axes of a multi-dimensional array. This operator works with flattened input model (or data), which are however multi-dimensional in nature and will be reshaped and treated as such in both forward and adjoint modes.

Parameters:
dims : tuple, optional

Number of samples for each dimension (None if only one dimension is available)

axes : tuple, optional

Direction along which transposition is applied

compute : tuple, optional

Compute the outcome of forward and adjoint or simply define the graph and return a dask.array.array

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

Raises:
ValueError

If axes contains repeated dimensions (or a dimension is missing)

Notes

Refer to pylops.basicoperators.Transpose for implementation details.

Attributes:
shape : tuple

Operator shape

explicit : bool

Operator contains a matrix that can be solved explicitly (True) or not (False)
