deleting duplicates in array using references

i have a multidimensional array, but i want to delete duplicate
entries based on the first element of each 'row'.
my array is:
my @array = ( [UK9004411, A140, B, 0.040] , [UK0030239, H7140, H,
0.030] , [UK0030239, S1393, M1, 0.030] , [UK0012821, H4030, H,
0.010] , [UK0012821, H4060, H, 0.010] );
and I want to end up with
( [UK9004411, A140, B, 0.040] , [UK0030239, H7140, H, 0.030] ,
[UK0012821, H4030, H, 0.010] )
(no real preference in which row is dropped...just on a first come
first served basis.)
i.e. take out the duplicate codes based on the first element of each
row $array[$row] -> [0]
i looked into splice() function based on the index but not sure this
is the best way or the syntax for this?
splice (@array , $row, 1); ?
thanks.
