Random line segments confined in a box

Hello everyone!
Does anyone know :
How can I create random line segments confined in a box ? Both of the edges of the line segments should touch the sides of the box.

figure;
axes('XLim', [-0.1, 1.1], 'YLim', [-0.1, 1.1]);
nLine = 100;
Coor = [0, 1, 1, 0, 0; ...
0, 0, 1, 1, 0];
for k = 1:nLine
edge1 = randi(4);
edge2 = randi(4);
P1 = Coor(:, edge1) + rand * (Coor(:, edge1 + 1) - Coor(:, edge1));
P2 = Coor(:, edge2) + rand * (Coor(:, edge2 + 1) - Coor(:, edge2));
line([P1(1), P2(1)], [P1(2), P2(2)]);
end
With this code the start and endpoint can be of the same edge. If you want different edges:
edge = randperm(4, 2);
edge1 = edge(1)
edge2 = edge(2);

@Jan Sorry to bother you but how would you do this in 3d?
