I have a vector (Y). I want to select a region from this vector. If this is a single region it is easy
X=Y(i_from:i_to);
What if I have several regions (the number of regions is not fixed)?
So I want to make the vector
[Y(i_from_1:i_to_1) ,Y(i_from_2:i_to_2), …….. ,Y(i_from_n:i_to_n)]
where n is not fixed.

Is there a fast and simple way? i_from and i_to values are in a n*2 matrix.
I can of course do a for cycle, but looking for a simpler method.I have a vector (Y). I want to select a region from this vector. If this is a single region it is easy
