Get unique rows with tolerance, matlab

I have the matrix

mat_=[1    1.25; 
      2    1.75;
      3    1.49; % Should be deleted as (abs(1.25-1.49)<.25) 
      4    1; 
      5    0.9; %(abs(1-.9)<.25)
      6    2.05];

I want to get a matrix with unique value and tolerance (e.g., tolerance=0.25). I made this matrix mat_unique manually just to explain my point

mat_unique=[1 1.25; 2 1.75; 4 1 ;6 2.05];

Any idea??

One approach -

tol=0.25 %// tolerance
mat_unique = mat_(~any(triu(abs(bsxfun(@minus,mat_(:,2),mat_(:,2).'))<tol,1)),:)
