Methods

 `ComputeStarDiscrepancy`(sample) Compute the star discrepancy of a sample uniformly distributed over [0, 1). `generate`(*args) Generate a sample of pseudo-random vectors of numbers uniformly distributed over [0, 1). Accessor to the object's name. Accessor to the dimension of the points of the low discrepancy sequence. Accessor to the object's name. Accessor to the linear congruential generator (LCG) used to scramble the sequences. Test if the object is named. `initialize`(dimension) Initialize the sequence. `setName`(name) Accessor to the object's name. `setScramblingState`(state) Accessor to the linear congruential generator (LCG) used to scramble the sequences.
__init__(*args)
static ComputeStarDiscrepancy(sample)

Compute the star discrepancy of a sample uniformly distributed over [0, 1).

Parameters:
sample2-d sequence of float
Returns:
starDiscrepancyfloat

Star discrepancy of a sample uniformly distributed over [0, 1).

Examples

```>>> import openturns as ot
>>> # Create a sequence of 3 points of 2 dimensions
>>> sequence = ot.LowDiscrepancySequence(ot.SobolSequence(2))
>>> sample = sequence.generate(16)
>>> print(sequence.computeStarDiscrepancy(sample))
0.12890625
>>> sample = sequence.generate(64)
>>> print(sequence.computeStarDiscrepancy(sample))
0.0537109375
```
generate(*args)

Generate a sample of pseudo-random vectors of numbers uniformly distributed over [0, 1).

Parameters:
sizeint

Number of points to be generated. Default is 1.

Returns:
sample`Sample`

Sample of pseudo-random vectors of numbers uniformly distributed over [0, 1).

Examples

```>>> import openturns as ot
>>> # Create a sequence of 3 points of 2 dimensions
>>> sequence = ot.LowDiscrepancySequence(ot.SobolSequence(2))
>>> print(sequence.generate(3))
0 : [ 0.5  0.5  ]
1 : [ 0.75 0.25 ]
2 : [ 0.25 0.75 ]
```
