Question: how can i get a unique list

eq:=[Vector[row](4, {(1) = 0., (2) = 0., (3) = 0., (4) = 0.}), Vector[row](4, {(1) = -0.3381778526e-2, (2) = -.3381778526, (3) = -.3185010532, (4) = 0.}), Vector[row](4, {(1) = 0., (2) = 0., (3) = 0., (4) = 0.}), Vector[row](4, {(1) = 0., (2) = 0., (3) = 0., (4) = 0.}), Vector[row](4, {(1) = 0., (2) = 0., (3) = 0., (4) = 0.})]

how i can get a unique results:[Vector[row](4, {(1) = 0., (2) = 0., (3) = 0., (4) = 0.}), Vector[row](4, {(1) = -0.3381778526e-2, (2) = -.3381778526, (3) = -.3185010532, (4) = 0.})]
