ParametricPointToFieldFunction

class ParametricPointToFieldFunction(*args)

Parametric Point to Field function.

It defines a parametric function from function by freezing the variables marked by the indices set to the values of referencePoint.

Parameters:
functionPointToFieldFunction

Function with full parameters from which the parametric function is built.

indicessequence of int

Indices of the frozen variables.

referencePointsequence of float

Values of the frozen variables. Must be of size of indices.

Methods

getCallsNumber()

Get the number of calls of the function.

getClassName()

Accessor to the object's name.

getFunction()

Function accessor.

getInputDescription()

Get the description of the input vector.

getInputDimension()

Get the dimension of the input vector.

getInputPositions()

Indices positions accessor.

getMarginal(*args)

Get the marginal(s) at given indice(s).

getName()

Accessor to the object's name.

getOutputDescription()

Get the description of the output field values.

getOutputDimension()

Get the dimension of the output field values.

getOutputMesh()

Get the output mesh.

getParameter()

Parameter accessor.

getParametersPositions()

Parameters positions accessor.

hasName()

Test if the object is named.

setInputDescription(inputDescription)

Set the description of the input vector.

setName(name)

Accessor to the object's name.

setOutputDescription(outputDescription)

Set the description of the output field values.

setParameter(parameter)

Parameter accessor.

Examples

>>> import openturns as ot
>>> size = 5
>>> mesh = ot.RegularGrid(0.0, 0.1, size)
>>> def f(X):
...     Y = [ot.Point(X)*i for i in range(size)]
...     return Y
>>> inputDim = 2
>>> outputDim = 2
>>> function = ot.PythonPointToFieldFunction(inputDim, mesh, outputDim, f)

Then create another function by freezing the parameter x2=5.0:

>>> g = ot.ParametricPointToFieldFunction(function, [1], [5.0])
>>> print(g.getInputDescription())
[x0]
>>> print(g([1.0]))
    [ y0 y1 ]
0 : [  0  0 ]
1 : [  1  5 ]
2 : [  2 10 ]
3 : [  3 15 ]
4 : [  4 20 ]
