I'm trying to estimate the possible points of intersection between two lines (arrays) in an image. Is there any function to return the values of the surrounding pixels for a particular value of the array?

Assuming it's a gray scale image, and that the row and column is not on the edge of the image:
surroundingWindow = grayImage(row-1:row+1, col-1:col+1);
If it's color:
surroundingWindow = rgbImage(row-1:row+1, col-1:col+1, :);

You'd need to do this:
[rows, columns] = find(abs(Pdist) > 50);
