Tuples

class Tuples(*args)

Tuples generator.

Available constructors:

Tuples()

Tuples(bounds)

Parameters:

bounds : Indices

The cardinal of all the sets forming the cartesian product.

Notes

In the first usage, the generator is built using the default values bounds = [1].

In the second usage, the generator produces all the indices [i_0, \ldots, i_{d-1}] with i_k \in \{0, \ldots, bounds[k] - 1\} where d is the dimension of bounds.

The number of indices generated is:

\prod_{k = 0}^{d - 1} bounds[k]

The tuples generator generates a collection of Indices that contains all the elements of the following Cartesian product:

\prod_{k = 0}^{d - 1} \{ 0, \ldots, bounds[k] -1 \}

Examples

>>> import openturns as ot
>>> tuples = ot.Tuples([3, 4])
>>> print(tuples.generate())
[[0,0],[1,0],[2,0],[0,1],[1,1],[2,1],[0,2],[1,2],[2,2],[0,3],[1,3],[2,3]]#12

generate()

Generate the combinatorial sequence.

Returns:

indicesCol : collection of Indices

The collection of all the possible values of the combinatorial generator as a set of non-negative integer values stored into an Indices.

getBounds()

Accessor to the bounds.

Returns:

bounds : Indices

The cardinal of all the sets forming the cartesian product.

getClassName()

Accessor to the object’s name.

Returns:

class_name : str

getId()

Accessor to the object’s id.

Returns:

id : int

Internal unique identifier.

getName()

Accessor to the object’s name.
