Plot a line, Hesse normal form parameterisation
Description
This is a simple interface over abline meant to be used along with the Hough transform. In the Hesse normal form (theta,rho), a line is represented as the set of values (x,y) such that cos(theta)*x + sin(theta)*y = rho. Here theta is an angle and rho is a distance. See the documentation for hough_lines.

nfline(theta, rho, col, ...)
Arguments

angle (radians) |
