Hi @SUSHMA MB

To calculate the coordinates of the points intersecting a polygon in MATLAB, you can use the polyxpoly function. This function finds the intersection points between two polygons or lines. Here's an example of how you can use it:

% Define the coordinates of the polygon vertices

xPolygon = [1, 3, 4, 2];

yPolygon = [1, 2, 4, 3];

% Define the coordinates of the line or other polygon to intersect with

xLine = [0, 5];

yLine = [2, 2];

% Calculate the intersection points

[xIntersect, yIntersect] = polyxpoly(xPolygon, yPolygon, xLine, yLine);

% Display the intersection points

scatter(xIntersect, yIntersect, 'r', 'filled');

hold on;

% Plot the polygon and line

plot(xPolygon, yPolygon, 'b');

plot(xLine, yLine, 'g');

% Additional plot settings

xlabel('X');

ylabel('Y');

title('Intersection of Polygon and Line');

legend('Intersection Points', 'Polygon', 'Line');
