Hello everyone,
I have a column which is 840 in length. It contains value s from -12 to 12. I need only values < -8 and >8. I need to keep the length 840. I tried the following. but it says " 0x1 empty double column vector".
v = zeros (size (data)); % Pre-allocate!
v=data(data <-8 & data>8)
thank you for helping.

Is it possible for a value to be smaller than -8 and greater than 8 at the same time? Check your logical operator. You need OR operator instead of AND.
v=data(data <-8 | data>8)
You can not keep the length same. If you want that, fill the other values with a specific value, like zero.
