Dear Artur and Allin, Thank you so much for your invaluable help. Now everything is working really fine! With the use of the Gretl scripting language I'm going to save a lot of time (these tasks are part of my PhD thesis).

Thank you so much for your invaluable help. Now everything is working
really fine! With the use of the Gretl scripting language I'm going to save
a lot of time (these tasks are part of my PhD thesis).

On that basis, here's an example:

<script>
matrix r = mshape(seq(1,144),12,12)
print r
scalar m = 7 # number of values to compute
scalar n = 6 # number of elements to sum
matrix R_n = zeros(m,1)
loop i=1..m -q
loop j=1..n -q
row = i + n - j
R_n[i] += r[row, j]
# see what's going on
printf "i=%d: adding r[%d,%d] (%g)\n", i, row, j, r[row, j]
endloop
endloop
print R_n
</script>
