use Array::Transpose qw{};
@array=Array::Transpose::transpose(\@array);
Example:
use Array::Transpose;
use Data::Dumper;
my $array=transpose([
[ 0 .. 4 ],
["a" .. "e"],

In linear algebra, the transpose of a matrix A is another matrix A' created by any one of the following equivalent actions:
write the rows of A as the columns of A'
write the columns of A as the rows of A'
reflect A by its main diagonal (which starts from the top left) to obtain A'

use Array::Transpose;
@array=transpose(\@array);
METHODS
