How to do sliding window operation in Matlab?

Suppose I Have a sequence

x=[4,1,1,1,2,2,3,5,9,7,7,7,6,6,1,1,2,3,4,4],

and I want addition for sliding window of size 10, i.e. addition of sequence

[4,1,1,1,2,2,3,5,9,7]

i.e. 4+1+1+1+2+2+3+5+9+7=35,then skipping 1st and adding next element of sequence i.e. addition for

[1,1,1,2,2,3,5,9,7,7],

then next i.e. addition for

[1,1,2,2,3,5,9,7,7,7]

likewise upto last window i.e.

[7,7,6,6,1,1,2,3,4,4],

how to do it.

R2016a has a new function movsum:

>> x=[4,1,1,1,2,2,3,5,9,7,7,7,6,6,1,1,2,3,4,4]
>> movsum(x,10,'EndPoints','discard')

ans =

      35    38    44    49    54    53    52    51    49    44    41

conv2(x,ones(1,10),'valid')

add

n = 10;
out = hankel(x(1:end-n+1),x(n+1:end));
