Shortest Distance Between Two Lines in N dimensions
Function uses algorithm from Dan Sunday internet site
http://softsurfer.com/Archive/algorithm_0106/algorithm_0106.htm#dist3D_Segment_to_Segment
L1, L2 includes two points in matrix of 2*n
where n are dimensions (3 in 3D).
d - shortest distance between two lines
Pc,Qc - points where exists shortest distance d
EXAMPLE:
L1=rand(2,3);
L2=rand(2,3);
[d Pc Qc]=distBW2lines(L1,L2)
Functions of lines L1,L2 and shortest distance line
can be plotted in 3d or with minor change in 2D by
removing comments sign from code at the end of the file.
In some cases points Pc,Qc will not displayed accurately on line.
Just change value of par parameter according to point.
