I have a n X 2 matrix, but I want remove the points with a distance smaller than a threshold. And the data is random, which means the data position may be very far in the matrix but their distance is very close. Can anyone help me?

dataOut = uniquetol(dataIn, tolerance, 'ByRows', true);
Above code should be a good starting point. In this case it would be 1-norm distance between points against given tolerance. Check uniquetol documentation for more information.
While it is not "Euklidean" 2-norm distance, in many cases should be good enough and it's very simple workaround.
