There isn't a "built-in" way, but one could write a hansl function to do
it. Here's a simple example.
...
or what about using the selecting function selifc():
set skip_missings off
matrix m = {L}
matrix result = {}
loop i=1..rows(m)
result |= meanr( selifc(m, ok(m[i])) )
# and analogous with sdc( selifc(...)' )'
endloop
series mymeans = result
(untested)
