Intersection of Two Lines (line_intersection) - File Exchange - MATLAB Central Intersection of Two Lines (line_intersection) Version 6. 3 Answers Sorted by: 1 if you have equations of the lines then you just need to solve 3 equations with two unknowns (x,y of intersection point). I've thought about using cell2mat() but . A = cell2mat (permute (struct2cell (a), [3 1 2])); B = cell2mat (permute (struct2cell (b), [3 1 2])); [C, ia] = intersect (A, B, 'rows'); c = a (ia); This way you don't need to explicitly specify all the struct fields. 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. Y; mesh (X,Y,Z1) hold on mesh (X,Y,Z2) I know I can find the locations of the elements of Z1 and Z2 where they are equal by setting a new array equal to (Z1==Z2), but that only gives me an arrays of 0s and 1s. c = intersect (A, B, 'rows') when A and B are matrices with the same number of columns returns the rows common to both A and B. A cross product returns the vector perpendicular to two given vectors. Find the values in A that are not in B as well as the index vector ia, such that C = A (ia). So apply yin = intersect (y1,y2); After this, since your x is sorted, you should check the value in yin that has the same index in both y1 and y2.
