Hi All--I have a matrix with plenty of zeroes, and I am trying to work with
elements above a cutoff percentile--and that percentile is defined among the
strictly positive elements. For example:
perldl> p $test=oddmedover($slice)
22
perldl> $a=sequence(10,5)

perldl> p $x=oddpctover($a,.5)
[4 14 24 34 44]
perldl> $slice=$a->where($a>$x->dummy)

perldl> $slice.=0

perldl> p $a

[
 [ 0  1  2  3  4  0  0  0  0  0]
 [10 11 12 13 14  0  0  0  0  0]
 [20 21 22 23 24  0  0  0  0  0]
 [30 31 32 33 34  0  0  0  0  0]
 [40 41 42 43 44  0  0  0  0  0]
]

So I can use oddpctover to get the median value of each row
unconditionally--how would I repeat that procedure on this censored matrix
(i.e. $x from above would return 2,12,22,32,42)?

Thanks,

Steve
