The problem's figure is missing. We can use our solution for problem 1720 (https://nl.mathworks.com/matlabcentral/cody/problems/1720-do-the-lines-intersect). However, line matrices are transposed in this problem. And for the picture, we can imagine an instance of Buffon's needle problem without horizontal lines.
