I have an application that is called with two points and returns the

Here is a better example, which produces the output I want to save.  The printf(...) statement displays the data I want to keep, in the order I want it.

Do you really want to recurse?

function [dist, mid] = gcr(p1,p2)
  p3 = p2 - p1;
  dist = sqrt(p3*p3');
  mid = (p1 + p2) ./ 2;
endfunction;

list = [1000,2000; 8000,9000];
idx = 1;
while idx < size(list,1)
  [distance, midpoint] = gcr(list(idx, :), list(idx+1, :));
  if distance > 300
    list = [list(1:idx, :); midpoint; list((idx+1):end, :)];
  else
    idx++;
  end
end
