Help reduce number of rows by grouping continous data

Hello,

as seen in the attached image, does anyone know how I can reduce the number of rows by grouping the first and last number of data that are squential. Ex) the first cell should say 20390-20400 because thats the first and last point in which continous data by differnce of 1 is present. the second row should say 22579-22588, then third row should say 25895-25904.

Thanks

d=find(diff(yourData)>1);
m=[yourData(1),yourData(d(1))];
for k=2:length(d)
   m(k,:)=[yourData(d(k-1)+1),yourData(d(k))];%generate matrix with beginning to end of each stream
end
m(end+1,:)=[yourData(d(end)+1),yourData(end)]
