  • One computational geometry question that we will want to address is how to determine the intersection of two line segments. This will allow for further solutions for more complex questions, including a general solution regarding whether a point is inside or outside of a convex or non-convex polygon. Previously, we’ve described how to define a line segment in MATLAB, and we will use this definition in our current method for solving for line intersections. Note: Much credit for this post and explanation should be given to Gareth Rees. While preparing this post, I ran across his response, and I can’t do it much more justice, so here is his general implementation in MATLAB. There are 5 possibilities if we have two line segments: 1) The two line segments are collinear and overlapping (intersecting portion is a line segment) 2) The two line segments are collinear and disjoint (not intersecting) 3) The two line segments are parallel (not intersecting) 4) Not parallel and intersect 5) Not parallel and non-intersecting

How to find the intersection of two lines? ›

FAQs on Intersection of Two Lines

Get the two equations for the lines into slope-intercept form. That is, have them in this form: y = mx + b. Set the two equations for y equal to each other. Solve for x.

What is the code for intersection in Matlab? ›

C = intersect( A,B ,___,'rows') and C = intersect( A,B ,'rows',___) treat each row of A and each row of B as single entities and return the rows common to both A and B , with no repetitions.

How do you find the intersection of two values? ›

To determine the points of intersection of two functions, you need to find the values of the independent variable (usually x) for which both functions have the same dependent variable value (usually y). In other words, you need to find the x-values for which the two functions are equal.

What is the formula for coordinates of point of intersection of two lines? ›

The point of intersection formula is used to find the point of intersection of the two lines, that is the meeting point of two lines. These two lines can be represented by the equation a1x+b1y+c1=0 and a2x+b2y+c2=0, respectively. It is possible to find point of intersection of three or more lines.

How do you find the intersection of two graphs? ›

We calculate it by solving the equation f(x) = 0 . When the graphs of y = f(x) and y = g(x) intersect , both graphs have exactly the same x and y values. So we can find the point or points of intersection by solving the equation f(x) = g(x).

How to find point of intersection of two lines in vector form? ›

By setting the values of x, y and z for these equations equal to one another, a value for both of the parameters can be found. These values can then be substituted back into the relevant vector equation to discover the point of intersection.

How to find the intercept of a graph in Matlab? ›

You can do that in MATLAB using the "find(diff(sign('your_data')))" and "interp1" refer to this code with the consideration of sample 2D arrays. t = linspace(0, 2*pi, 1000); ph = -rand(10,1);

How do you find the intersection of two sets in math? ›

For any two sets A and B, the intersection, A ∩ B (read as A intersection B) lists all the elements that are present in both sets (common elements of A and B). For example, if Set A = {1,2,3,4,5} and Set B = {3,4,6,8}, A ∩ B = {3,4}.

What is the intersection of two number lines? ›

Answer: A coordinate plane is formed by two number lines that intersect at right angles. The point of intersection is the ZERO on each number line – it is called the origin. The two number lines are called the axes.

What is the area of intersection in Matlab? ›

area = rectint(A,B) returns the area of intersection of the rectangles specified by position vectors A and B .

How do you find intersection with Fzero in Matlab? ›

Using fzero() to find the intersection of 2 functions. Assume you have functions y1(x) and y2(x). Create a new function y3(x) = y1(x) - y2(x). The zero of y3(x) is the intersection of y1(x) and y2(x).

How do you find the point of intersection of two planes? ›

1. Take the cross product of the normal vectors to find the directional vector of the line of intersection: n → α × n → β = ( 1 , 2 , − 3 ) × ( 1 , − 1 , 2 ) = ( 4 − 3 , − 3 − 2 , − 1 − 2 ) = ( 1 , − 5 , − 3 ) . 2. Set z = 0 and solve the system of equations to find the point P .

How do you find the intersection of two events? ›

We apply P(A ∩ B) formula to calculate the probability of two independent events A and B occurring together. It is given as, P(A∩B) = P(A) × P(B), where, P(A) is Probability of an event “A” and P(B) = Probability of an event “B”.

How do you find the intersection of two spaces? ›

How to find the intersection of two linear spaces - Quora. Let the two linear spaces be U and V . Their intersection is a subspace of both of them : W = U ∩ V : x ∈ W <==> [ x ∈ U and x ∈ V ] .
