Sorting 2 row columns

I have two colums
for example
x=[0.5 0.8 0.9 0.9 0.9 1]
y=[2 1.8 1.6 1.5 1.2 1.1]
I want to obtain this result
x=[0.5 0.8 0.9 1]
y=[2 1.8 1.2 1.1]
The lowest y-value that occurs for the x-value (that occurs multiple times), needs to be sorted.

[x, ~, id] = unique(x);
y = accumarray(id, y, [], @min)';
