% Test formula to calculate the distance between two points
% in the cartesian plane.  Use performDiffTest function to 
% partially automate the testing. 

% Use tolerance of 0.001 since calculation involves a square root.

performDiffTest( distance(1,5,-2,1), 5, 0.001, '1');
performDiffTest( distance(-2,-3,-4,4), 7.28, 0.001, '2');
