Indices¶
- class Indices(*args)¶
Collection of unsigned integers.
- Available constructors:
Indices(size=0, value=0)
Indices(sequence)
- Parameters
- sizeint,
Size of the collection.
- valuepositive int
Value set to the size elements.
- sequencesequence of int
Components of the vector.
Examples
>>> import openturns as ot
Use the first constructor:
>>> ot.Indices(3) [0,0,0] >>> ot.Indices(3, 4) [4,4,4]
Use the second constructor:
>>> vector = ot.Indices([100, 30, 70]) >>> vector [100,30,70]
Use some functionalities:
>>> vector[1] = 20 >>> vector [100,20,70] >>> vector.add(50) >>> vector [100,20,70,50]

- __init__(*args)¶
- add(*args)¶
Append a component (in-place).
- Parameters
- valuetype depends on the type of the collection.
The component to append.
Examples
>>> import openturns as ot >>> x = ot.Point(2) >>> x.add(1.) >>> print(x) [0,0,1]
- at(*args)¶
Access to an element of the collection.
- Parameters
- indexpositive int
Position of the element to access.
- Returns
- elementtype depends on the type of the collection
Element of the collection at the position index.
- check(bound)¶
Check that no value is repeated and no value exceeds the given bound.
- Parameters
- boundpositive int
The bound value.
- Returns
- checkbool
True if no value is repeated and all values are < bound.
- clear()¶
Reset the collection to zero dimension.
Examples
>>> import openturns as ot >>> x = ot.Point(2) >>> x.clear() >>> x class=Point name=Unnamed dimension=0 values=[]
- complement(n)¶
Build the complement of the current indices wrt .
- Parameters
- boundpositive int
The value of .
- Returns
- complement
Indices
The increasing collection of integers in not in the current indices.
- complement
Examples
>>> import openturns as ot >>> indices = ot.Indices([1, 3, 4]) >>> print(indices.complement(7)) [0,2,5,6]
- fill(initialValue=0, stepSize=1)¶
Fill the indices with a linear progression.
Starting from the start value initialValue by step stepSize.
- Parameters
- initialValuepositive int
Initial value. By default it is equal to 0.
- stepSizepositive int
Step size. By default it is equal to 1.
Examples
>>> import openturns as ot >>> indices = ot.Indices(3) >>> indices.fill() >>> print(indices) [0,1,2] >>> indices = ot.Indices(3) >>> indices.fill(2, 4) >>> print(indices) [2,6,10]
- find(val)¶
Find the index of a given value.
- Parameters
- valcollection value type
The value to find
- Returns
- indexint
The index of the first occurence of the value, or the size of the container if not found. When several values match, only the first index is returned.
- getClassName()¶
Accessor to the object’s name.
- Returns
- class_namestr
The object class name (object.__class__.__name__).
- getId()¶
Accessor to the object’s id.
- Returns
- idint
Internal unique identifier.
- getName()¶
Accessor to the object’s name.
- Returns
- namestr
The name of the object.
- getShadowedId()¶
Accessor to the object’s shadowed id.
- Returns
- idint
Internal unique identifier.
- getSize()¶
Get the collection’s dimension (or size).
- Returns
- nint
The number of components in the collection.
- getVisibility()¶
Accessor to the object’s visibility state.
- Returns
- visiblebool
Visibility flag.
- hasName()¶
Test if the object is named.
- Returns
- hasNamebool
True if the name is not empty.
- hasVisibleName()¶
Test if the object has a distinguishable name.
- Returns
- hasVisibleNamebool
True if the name is not empty and not the default one.
- isEmpty()¶
Tell if the collection is empty.
- Returns
- isEmptybool
True if there is no element in the collection.
Examples
>>> import openturns as ot >>> x = ot.Point(2) >>> x.isEmpty() False >>> x.clear() >>> x.isEmpty() True
- isIncreasing()¶
Check if the indices are increasing.
- Returns
- isIncreasingbool
