"Squeeze" array of indexes.

There must be an elegant way to do this in MATLAB.
Let's say I have an array of points and I want to find all areas where the points are over 0.90.
gap_indexes = find(output > 0.90)
Now you have indexes to all locations where output is greater than 0.90. But let's say you don't care about when there are two 0.90s right next to each other. What's the best way to squeeze them out into 1 index (let's say the later index)?

I think it would be a good idea for you to give a specific example of the variable "output" (which is your input!), and what you prefer to see for gap_indexes.

% Run length encoding:
A = rand(100,1)>.9;
find(diff([A; false]) == -1)
If you want the first change -1 to 1.
