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)

Inputs

• l1 (1×1, 1×2, 1×3, or 1×4 double) vector defining line 1:
  • [x1]: vertical line form,
  • [m1,b1]: slope-intercept form,
  • [x1,y1,m1]: point-slope form,
  • [x1,y1,x2,y2]: two point form,
• l2 (1×1, 1×2, 1×3, or 1×4 double) vector defining line 2:
  • [x2]: vertical line form,
  • [m2,b2]: slope-intercept form,
  • [x2,y2,m2]: point-slope form,
  • [x3,y3,x4,y4]: two point form,

Outputs

• x_int (1×1 double): -coordinate of line intersection,
• y_int (1×1 double): -coordinate of line intersection,
