make_ellipse_data_points#

pyxem.utils.ransac_ellipse_tools.make_ellipse_data_points(x, y, a, b, r, nt=20, use_focus=True)[source]#

Get an ellipse position list.

Parameters:

x, y (scalars) – Centre position of the ellipse.
a, b (scalars) – Semi lengths
r (scalar) – Rotation, in theta
nt (int, optional) – Number of data positions, default 20
use_focus (bool) – If True, (x, y) will be the focus. If False, (x, y) will be centre of the ellipse.

Returns:

data – [[x0, y0], [x1, y1], …]

Return type:

numpy.ndarray

Examples

>>> import pyxem.utils.ransac_ellipse_tools as ret
>>> data = ret.make_ellipse_data_points(5, 9, 8, 4, np.pi/3)

Using all the arguments

>>> data = ret.make_ellipse_data_points(5, 9, 8, 4, 0, nt=40,
...                                     use_focus=False)
