[the cyclist]

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.

[FIR]

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

Answer 1

[Andrei Bobrov]

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.
