Hi PerlMonks


I have a function which has 2 inputs, one is a scalar and the other is a 1D array,

the function returns a 1D array,
    #####
    sub mult {

               my ($a, @b) = @_;
        :    :
        return @c;
        }
    ####

when the function is called $N times, say, I want to store the $N results in a 2D array 
   ####
   for $i (0..$N){
       @results  = mult($a,@b[$i]);
       }
   ####

but the above code gives me a very long 1D array, and the following code doesn't compile
   ####
   for $i (0..$N){
       @results[$i][]  = mult($a,@b[$i]);
       }
   ####

trying to manipulate 2D arrays is wrecking my head,

and I'd appreciate any help.

Thanks

Damian
