9.9. Slicing¶

class cherab.core.math.slice.Slice2D¶

Exposes a slice of a Function2D as a Function1D.

Parameters:

function (Function2D) – the function to be sliced.
axis – the axis to be sliced. Must be [‘x’, ‘y’] or [0, 1].
value (float) – the axis value at which to return a slice

>>> from cherab.core.math import Slice2D
>>>
>>> def f1(x, y):
>>>     return x**2 + y
>>>
>>> f2 = Slice2D(f1, 'x', 1.5)
>>>
>>> f2(0)
2.25
>>> f2(1)
3.25

class cherab.core.math.slice.Slice3D¶

Exposes a slice of a Function3D as a Function2D.

Parameters:

function (Function3D) – the function to be sliced.
axis – the axis to be sliced. Must be [‘x’, ‘y’, ‘z’] or [0, 1, 2].
value (float) – the axis value at which to return a slice

>>> from cherab.core.math import Slice3D
>>>
>>> def f1(x, y, z):
>>>     return x**3 + y**2 + z
>>>
>>> f2 = Slice3D(f1, 'x', 1.5)
>>>
>>> f2(0, 0)
3.375
>>> f2(1, 0)
4.375
