Intersection of Two Lines (line_intersection)

Finds the intersection of two lines.

line_intersection

Finds the intersection of two lines.

Syntax

[x_int,y_int] = line_intersection(l1,l2)

Description

[x_int,y_int] = line_intersection(l1,l2) returns the intersection [x_int,y_int] of two lines.

• Line 1 can be defined in four different ways:

  1. l1 = x1: vertical line form (vertical line defined as )
  2. l1 = [m1,b1]: slope-intercept form ()
  3. l1 = [x1,y1,m1]: point-slope form ()
  4. l1 = [x1,y1,x2,y2]: two point form (line that contains the points and )

• Line 2 can be defined in four different ways:

  1. l2 = x2: vertical line form (vertical line defined as )
  2. l2 = [m2,b2]: slope-intercept form ()
  3. l2 = [x2,y2,m2]: point-slope form ()
  4. l2 = [x3,y3,x4,y4]: two point form (line that contains the points and )
