How can I segment a matrix based on the difference between a column's elements of the matrix?

I have a matrix (X), I want it to be segmented such that for each segment, the difference between successive first column entries does not exceed 6. The output should be as (xx) or call it whatever.

%%% The INPUT %%%
X=[
    8.3700  -53.3090
    11.4000 -116.6670
    13.0000 -117.8350
    26.7000 -105.8580
    36.4000 -121.5060
    39.4000 -116.0400
    65.1000  -95.1370
    65.9000 -123.0920
    70.3000 -133.5950
    122.0000 -113.7320
    ]

X=[
    8.3700  -53.3090
    11.4000 -116.6670
    13.0000 -117.8350
    26.7000 -105.8580
    36.4000 -121.5060
    39.4000 -116.0400
    65.1000  -95.1370
    65.9000 -123.0920
    70.3000 -133.5950
    122.0000 -113.7320
    ];
i = find(abs(diff(X(:,1)))>6);
i = [i(1);diff(i);size(X,1)-i(end)];
xx = mat2cell(X,i)

xx = 5×1 cell array
    {3×2 double         }
    {[26.7000 -105.8580]}
    {2×2 double         }
    {3×2 double         }
    {[    122 -113.7320]}
