For example:

function matrix deselected (list L1, list L2)
matrix vd = L1
loop i=1..cols(vd) --quiet
vd[i] = !inlist(L2, L1[i])
endloop

open data4-10
ols 1 0 2 3 4 5 6
L1 = $xlist
omit --auto=.05
L2 = $xlist
matrix Ldiff = deselected(L1, L2)
print Ldiff

Or, alternatively,
<hansl>
function matrix deselected (list L1, list L2)
matrix m1 = L1
matrix m2 = L2
return !sumc(m1 .= m2')
end function
