Intersecting Lines

Download code from

A line can be defined parametrically

The shortest distance from a point to a line is the perpendicular vector d

The intersection of two parametric lines can be found from

See perp.m for example code.

The intersection of more than two lines can be found by minimizing the sum of the squared distances from the solution point to each of the intersecting lines.
The method is given in intersect_lines.m

See perp_script3.m for this example
