the 
grep{$_} .......

[download]
also removes "" and 0 from the list. Should probably be 
grep{defined $_} .....

Also - why use 
@array -1

[download]
when you could use 
$#array

[download]
I like the approach.... Perhaps 
map{[
   grep {defined}
   @array[$_*$len..$_*$len+$len-1]
   ]} 0..$#array/$len

Is a little cleaner?
