Mean column with step

I have a column vector of n elements, i would like to calculate the mean with a step of 10 (the mean of 10th, 20th, and so on). thanks

Or maybe you mean this,

out = mean(theVector(10:10:end))

I think this, may aim us to compute the mean of 10ith, 20th, 30th... If we assume that the vector reflects daily profits, i would like to compute over the full period (length of the vector) the average profit each 10 days! Thank you for your reply

Assuming n is a multiple of 10 (otherwise you should pad the vector), you can use SEPBLOCKFUN (Download),

out = sepblockfun(theVector,[10,1],'mean')

I think this is not my aim, the output will be a simple number, which is the mean each 10th elements in the vector, with this function sepblockfun i get a vector as output
