I have x & y coordinates for 2 points on a graph, 29 total graphs for each point. I need to loop through these coordinates for find the distance between the two points and then take the average. Right now I have x1 in a 29 x 1, y1 in a 29 x 1, x2 in a 29 x 1, and y2 in a 29 x 1. How do I loop through these points and find the distance between them?

average = mean(sqrt((x2-x1).^2+(y2-y1).^2));

My variables for the coordinates are all stored in 1x29 arrays. How do I write a for loop to loop through the 4 arrays, pulling out the corresponding x & y for the 2 points?

The above code is designed to handle 1-by-29 arrays, all in one line. You don't need a for-loop for this task. Try it and see.
