EDIT __________
my apolgies for confusion
Say I have a matrix of nx1 as such:
[..... 2.59, 2.6, 2.6, 1.7 , ....... , 1.8 , 2.57 , 2.6, 2.7, 1.8.....]
(block 1) (block 2)
Is there a function that groups that first "block" of values over 2.5 as "block 1" and then the second "block" of values over 2.5 as another thing such as "block 2"
my apologies I appreciate your help

We're not going to type that in. Please attach the data with the paperclip icon. Make it easy for people to help you, not hard.

If you have Image Processing Toolbox, you can do this task easier by using bwlabel function. The following is a simple example.
nx1 = [1.1, 2.59, 2.6, 2.6, 1.7, 1.8, 2.57, 2.6, 2.7, 1.8];
idx = nx1 > 2.5;
group = bwlabel(idx);
The result is like:
>> group
group =
0 1 1 1 0 0 2 2 2 0
