Hello All,
Problem:
Need to extract values ranging from index 1 to 5 and write
it into a new variable.
Then take index 6 to 10 and write it into the next variable....
Basically extract a range of 5 indices from start to end and write each into
a variable.
Question: do you use a loop or some sort of index mechanism?

Thanks

Extract the values from what? A structure? A cell array? A textfile?

Perhaps a small example which captures the relevant features of your problem would be appropriate.

You DON'T do it at all.

Learn to use cell arrays, so you can assign all of
these "variables" into one single cell array with the
function mat2cell.

Matt,
you right, this example is not very descriptive. Maybe this helps.
source data is a column vector, e.g
data = [1:15]'
result should be
t1 = data(1:3);
t2 = data(4:6);
t3 = data(7....

I just wanted to test the mechanism, the actual data is well over 10e6 values.

In that case, I would not do what you are thinking of doing. Do as John suggested, use a cell array. You can even use MAT2CELL to break it up as you wish.
