infty_sign(n=100, noise=None, angle=None, seed=None)¶
Construct a figure 8 or infinity sign with
npoints and noise level with
n (int) – number of points in returned data set.
noise (float) – standard deviation of normally distributed noise added to data.
angle (float) – angle in radians to rotate the infinity sign.
seed (int) – Seed for random state.
