-
class
pylops_distributed.
HStack
(ops, chunks=None, compute=(False, False), todask=(False, False), dtype=None)[source]¶ Horizontal stacking.
Stack a set of N linear operators horizontally.
Parameters: - ops :
list
Linear operators to be stacked
- chunks :
tuple
, optional Chunks for model and data (an array with a single chunk is created if
chunks
is not provided)- compute :
tuple
, optional Compute the outcome of forward and adjoint or simply define the graph and return a
dask.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.
