Intersection Of two curves

Intersection Of two curves in Pure numpy

Inspired from this matlab implementation, wrote this python implementation of how to detect intersection of two curves.

Example usage

from intersect import intersection

a, b = 1, 2
phi = np.linspace(3, 10, 100)
x1 = a*phi - b*np.sin(phi)
y1 = a - b*np.cos(phi)

x2 = phi
y2 = np.sin(phi)+2
x, y = intersection(x1, y1, x2, y2)

plt.plot(x1, y1, c="r")
plt.plot(x2, y2, c="g")
plt.plot(x, y, "*k")
plt.show()
