class minkit.marray(array, dtype, length=None, backend=None)

Bases: object

Wrapper over the arrays to do operations in CPU or GPU devices.

Parameters

• array (numpy.ndarray or reikna.cluda.api.Array) – original array.

• int – (GPU only) actual size of the array.

• backend (Backend) – backend where to put the array.

Attributes Summary

aop	Associated object to do array operations.
backend	Backend interface.
dtype	Data type.
length	Length as a numpy.int32 instance.
shape	Shape of the array.
ua	Underlying array.

Methods Summary

as_ndarray()	Return the underlying array as a numpy.ndarray instance.
copy()	Copy this array.
from_ndarray(a, backend)	Create this class from a numpy.ndarray instance.
get(i)	Get an element of the array.
to_backend(backend)	Send the array to the given backend.

Attributes Documentation

aop

Associated object to do array operations.

backend

Backend interface.

dtype

Data type.

length

Length as a numpy.int32 instance.

shape

Shape of the array.

ua

Underlying array.

Methods Documentation

as_ndarray()

Return the underlying array as a numpy.ndarray instance. If the underlying array is already of this type, no copy is done.

Returns

underlying array as a numpy.ndarray.

Return type

numpy.ndarray

copy()

Copy this array.

Returns

Copy of this array.

classmethod from_ndarray(a, backend)

Create this class from a numpy.ndarray instance.

Parameters

• a (numpy.ndarray) – array.

• backend (Backend) – backend where to create this array.

Returns

Newly created array.

get(i)

Get an element of the array. The output type depends on the type of array.

Parameters

i (int) – index.

Returns

value at the given index.

Return type

float, int or bool

to_backend(backend)

Send the array to the given backend.

Parameters

backend (Backend) – backend where to transfer the array.

Returns

this array on a new backend.

Return type
