I have 8*1 matrix.
I want to extract the first four element( 1st to 4th position) in new vector and last 2 element(7&8 position). How can I do it?
x1 =[6856.06600000000
65128.6516000000
6881.95430000000
65135.3738000000
6810.99550000000
65302.1415000000
6836.86630000000
65308.8605000000]
So my new vector will be
new =[6856.06600000000
65128.6516000000
6881.95430000000
65135.3738000000
6836.86630000000
65308.8605000000]

This should work
new = [x1(1:4)]
new = [new; x1(end-1:end)]
Thanks,
Nikhil
