Unique (partial) values

Hi all! I have a cell array (imported by xlsread) of this kind:

    '0.000000000'    '185.47.162.26' 
    '0.000658000'    '185.47.169.249'
    '0.000793000'    '177.10.146.49' 
    '0.003146000'    '185.47.162.26' 
    '0.006683000'    '185.47.162.26'

Now...i'm interested to select only rows corresponding to the first unique values of second column. So...in this example i need the following output:

    '0.000000000'    '185.47.162.26' 
    '0.000658000'    '185.47.169.249'
    '0.000793000'    '177.10.146.49'

Unique function seems not to support a feature like this. Can you help me? Thx in advance! Mario

[~, idx] = unique(YourCellArray(:,2), 'stable');
output = YourCellArray(idx, :);
