Apr 3, 2020 · I am trying to find the places where each of my curves intersects the line y=0.01 on matlab. How can I do this? Here is what I have wrote so far to try: %Finding Equations of Curves p=polyfi...

Dec 17, 2020 · If you have two vectors, x1, y1 that form the curve (x1, y1), and likewise, another curve (x2, y2), then you can get the intersection points using the function by Douglas Schwarz. https://www.mathworks.com/matlabcentral/fileexchange/11837-fast-and-robust …

Feb 20, 2021 · The simplest solution is to use the intersections () function from the file exchange (I show a similar demo in this answer, "method #2"). That function will return the (x,y) coordinates of the intersection points. Use the x values to plot vertical lines using xline (). In your demo of "method #2", X1 and Y1 must be of same size.

May 5, 2013 · Use vpa(intersection) to convert it to a number or double(intersection) to convert it to a floating point value. Last but not least, perhaps the cleanest way to do this is the command polyxpoly: Good luck!

May 13, 2017 · 1) If your discretization : x=0:0.05:2; do contain the intersection point, you can use the intersect function in Matlab. For example. will return a vector with two elements 1 and 3, the intersection of those two vectors. To find the intersection point is to find the point x such that y1 (x)=y2 (x). So apply.

Oct 14, 2015 · I'm new in matlab and I'm trying to find the intersection between a curve (from points) and a line. I've some points and I've plot the interpolation between this points. Now I want to find the intersection between the interpolation (xi,yi) curve and another line.

Feb 4, 2022 · f = @(z) interp1(x,y-c,z); % Creates anonymous function representing the difference between curve and straight line

The simplest solution is to use the intersections () function from the file exchange (I show a similar demo in this answer, "method #2"). That function will return the (x,y) coordinates of the intersection points. Use the x values to plot vertical lines using xline (). Or, if you're more comfortable with for-loops,

Feb 28, 2018 · To find the intersection between a ray and a line segment we can do the following. Given the points at the endpoints of the line segment which we call p1 and p2 and a ray beginning at A and passing through C, we solve the vector equation p1 + t1*(p2-p1) == A + t2*(C-A) for scalars t1 and t2.

The meaning of those intersections is that the given lines or curves have the same coordinate values at some points. In other words, those lines or functions have simultaneously the same x and y (or even z ) values at those points called intersections.
