This gives the shortest distance between any line and a point. We will find the distance RS, which I hope you agree is equal to the distance PQ that we wanted at the start. If t is between 0.0 and 1.0, then the point on the segment that is closest to the other point lies on the segment.Otherwise the closest point is one of the segment’s end points. We consider three cases: The difference between these cases becomes clear when we consider the intersection point of the line through A and B and the perpendicular through P. The closest point can be the intersection point, or A, or B: This approach provides insight, but is limited: we need a ruler to measure the distance, an it only works in 2D. I tried to use this formula : |Ax+By+C| / sqrt(A^2+B^2) , but i messed up and got more confused by the minute (mostly because of … The ability to automatically calculate the shortest distance from a point to a line is not available in MATLAB.
