MATLAB: How do you remove duplicates of nested cells

Question

I have cell array that looks like the following:

RomanticGestures = ...                           % Cell array 5x1
                    {{List of Flowers};...       % nested Cell array 15x1
                    {List of Chocolates};...     % nested Cell array 15x1
                    {List of Movies};...         % nested Cell array 17x1
                    {List of Flowers};...        % nested Duplicate Cell array 15x1
                    {List of Wines}};...         % nested Cell array 34x1

But I do not need the nested cell that contains the list of flowers twice. So this is what I want:

RomanticGestures = ...                      % Cell array 5x1
                    {{List of Flowers};...  % nested Cell array 15x1
                    {List of Chocolates;... % nested Cell array 15x1
                    {List of Movies};...    % nested Cell array 17x1
                    {List of Restaurants}}; % nested Cell array 34x1
    

I also need to know what row the duplicate occured in.

have tried unique but I think I have the notation wrong. I have tried:

RomanticGestures=unique(RomanticGestures)

Also

RomanticGestures=unique(cell2mat(RomanticGestures),'rows')

cell2mat doesnt work.

Any suggestions are appreciated 🙂 Thank you!

Sounds like:

Dates{1} = unique(Dates{1});  %What a misleading variable names if it doesn't contain dates/times!

is what you're after.
