Remove duplicate values in matrix

Hi, I have following code:

a_x = 1.5:0.2:a_max;
a_y = 1.5:0.2:a_max;
a = zeros(length(a_x),length(a_y));
for i = 1:length(a_x)
    for j = 1:length(a_y)
        a(j,i) = (a_x(i)+a_y(j))/2;
    end
end

I would like to remove all duplicate values in a, and turn this in a vector with ascending value. Any idea how?

unique(a) %EDITED

unique already return the values sorted (unless the 'stable' option is used), so the sort is redundant.

Ah, Thanks Guillaume . Edited!
