I'm working on a path following vehicle. I have a matrix with the coordinates of the path and I have the actual position of the car. And I want to know what is the next point of the path closest to the actual position. How do I do that?

Basically, I want to know what is the point of the path closer to the point of the actual position.

Wouldn't you just use the Pythagorean theorem to get the closest distance?
distances = sqrt(pathX - actualX).^2 + (pathY - actualY).^2);
[closestDistance, indexOfClosestPoint] = min(distances);
closestPathX = pathX(indexOfClosestPoint);
closestPathY = pathY(indexOfClosestPoint);
