points = detectSURFFeatures(I);
xxyy = points.Location;
xyxy = reshape( xxyy.', 1, []);
That is, xxyy is an M x 2 array in which the x are the first column and the y are the second column. But you want a row vector in which the x and y alternate, so it is necessary to transform the 2D array to get the vector you want. (Personally I think the 2D array is a lot easier to work with...)
