Please edit your question to provide much more detail about what you want. It is not possible to understand what you mean. For example:
How are your 4026 data stored?
What do you mean by "top 100"?
How do you want to choose the 2 data from the 100? Should it be random?
Etc.
Remember we know NOTHING about your problem except what you tell us here.

data are stored as
data=[1,2,3........4026]
top 100 means 1st 100,2nd 100,3rd100..so tere are (41 100's)
1&2 from 1st100
101*102 from 2nd 100
201&202 from 3rd 100

'
'
'3901*3902
4001&4002 from last hundred

data = 1:4026;
out = sort(data([1:100:end,2:100:end]));
or
out = data([1:100:end;2:100:end])'
or
out = bsxfun(@plus,sort([randi(100,floor(4026/100),2);randi(26,1,2)],2),(0:100:4000)');

That is a different interpretation to mine. I wonder if either of us are even close.
