More simpler way:
[C,~,~]=unique(v);
val=sum(v)-sum(C)
Edit after Image Analyst's warning:(works for any situation)
[C,~,idx]=unique(v,'stable');
n=accumarray(idx(:),1);
vals=C(find(n~=1))

Hareesha, it looks like you accepted Birdman's answer, and that doesn't require the stats toolbox, so go with that.

Here is one way:
v = [...
104.96
81.01
-35.21
-150.76
145.22
104.96
20.62
-90.79]
distances = pdist2(v, v) % In Stats toolbox
% Find where distances = 0
[rows, columns] = find(distances == 0)
for k = 1 : length(rows)
if rows(k) ~= columns(k) % Ignore diagonals
fprintf('Element at row %d (%f) is a repeat.\n', rows(k), v(rows(k)));
end
end
It shows:
Element at row 6 is a repeat.
Element at row 1 is a repeat.
