I have data
m= 1 8 3 3 3 8 4 1 8 4 1 6 7 10 10 8 6 8 6 8 6 3 3 8 3 9....
with sequence length 2000. with this data I made transition probability matrix p

and initial probability matrix r

now I want to select data with window size 10, so 10 elements of m i.e. 1 8 3 3 3 8 4 1 8 4 are selected. I want to take sum of log of transition probability and initial probability of corresponding selected elements of m. i.e. 1 8 3 3 3 8 4 1 8 4 are selected so
log(r1)+log(r3)+log(r4)+log(r8)+log(p11)+log(p13)+log(14)+log(18)+log(31)+log(33)+log(34)+log(38)+log(41)+log(43)+log(44)+log(48)+log(81)+log(83)+log(84)+log(88)
in above r1,r3,r4,r8 are initial probability and p11,p13... are transition probability. so above result would be one single value, now same above thing I want to do with sliding window by 1 position to next i.e. skipping previous element and adding next element so selected elements of m will be 8 3 3 3 8 4 1 8 4 1. how to do this for sliding window upto end. each window operation give one value so window operation value should be accumulate in one variable. how to do this.
