Find the distance from your (x,y) coordinate location to all other node locations (let's say they're defined by variables named allX and allY), then use min() to find out which one is closest to your target (x,y) point:
distances = sqrt((x - allX) .^ 2 + (y - allY) .^ 2);
[minDistance, indexOfClosestNode] = min(distances);
