Getting the central n numbers in array..

Is there an easy way to get central n numbers in an array?for eg x=[ 1 2 3 4 5] I want to extract the central 3 numbers (i.e) 2,3 and 4.Which is the shortest way to do that?

Answer 1

[Walter Roberson]

To extract the middle N elements of the vector x:

x((end-N)/2+1:(end+N)/2)

Warning: this will cause an error if you ask for an odd number of elements from a vector of even length, or an even number of elements from a vector of odd length.
