[DISTANCES PROJ_POINTS]=DISTANCE2LINE(POINTS,LINE_SEG)
This function distance2line computes minimum euclidean distances (vertical distances) of "points" (nxm matrix which m=2,3) to a "line" (1xm which m=2,3). The input "line" is defined by its two points that lying on this line

The output "distances" is a nx1 vector matrix consisting of distances of points to the line. The second output "proj_points" is also a nxm matrix and this matrix gives the coordinates of vertically projected points onto the line.

I did not include any input error checking for the speed considerations because i use this function in a loop in MATLAB. So this function must be used with care.

You can use the provided example file for usage.
