Find the mean of every 5 values in an array

Hi, so I have an array of double

b=[ 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0]

How do I obtain the mean of every 5 values?

Lanceric - try using reshape to change your array from a 1x20 to a 5x4 array and then compute the mean from that. For example,

 mean(reshape(b,[5,4]))
