Hello all,
Suppose I have a double with 15 rows. I want to take data from the first four lines in every set of five and skip the fifth row. How can I express this in a for loop? Thanks

Do you want each iteration to take 4 rows and skip the 5th, OR do you
want that to happen over 5 iterations (so that you're only taking one
row per iteration)?

A for loop can run over any array, not just a consecutive array. That is, instead of:

for ix = 1:15
...
end

you can use:

for ix = [1:4 6:9 11:14] % only first four of each five indices
...
end

Do you need a FOR loop? It would have helped to give more context.

If the data is not large, you could do this:

a=(1:15)' %example data with 15 rows
b=a; %make a copy
b(5:5:end,:)=[] %delete every 5th row

I would like to take 4 rows and skip the 5th for each iteration.
