find intersection of two lines in hesse normal form in matlab in matlab

To find the intersection point of two lines in Hesse normal form in MATLAB, we can use the following code:

main.m
function intersection = hesse_intersection(A1, D1, A2, D2)
% Find intersection point of two lines in Hesse normal form
% A1, D1 - coefficients of the first line
% A2, D2 - coefficients of the second line

% Compute the intersection point
w = cross(A1, A2);
if abs(w(3)) < eps % the lines are parallel
    intersection = [];
else
    intersection = cross(w, D1+D2);
    intersection = intersection / intersection(3);
end

Where A1 and A2 are 3-element vectors containing the coefficients a, b, and c of the Hesse normal form of the first and second lines, respectively, and D1 and D2 are the distances of the lines from the origin. The function returns the intersection point as a 3-element vector (x, y, 1).

Here's an example usage of the function:

main.m
A1 = [1 2 3];
D1 = 4;
A2 = [-2 1 5];
D2 = -6;

intersection = hesse_intersection(A1, D1, A2, D2);
fprintf('Intersection point: (%.2f, %.2f)\n', intersection(1), intersection(2));

This will output the computed intersection point of the two lines in Hesse normal form.
