Tuples

class Tuples(*args)

Tuples generator.

Parameters:
boundsIndices

The cardinal of all the sets forming the cartesian product.

Methods

generate()

Generate the combinatorial sequence.

getBounds()

Accessor to the bounds.

getClassName()

Accessor to the object's name.

getName()

Accessor to the object's name.

hasName()

Test if the object is named.

setBounds(bounds)

Accessor to the bounds.

setName(name)

Accessor to the object's name.

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
