Unique cell of MATLAB memory cell2mat

Question

I created an array of arrays like this

A{1} = {'aa','b','d','aa'};
A{2} = {'c','d','aa'};
A{3} = {'bb','aa','bb','aa'};

now i want to find unique words

b=cell2mat(A)
unique(b)

but I get this error: Error using cell2mat (line 52) Cannot support cell arrays containing cell arrays or objects

.

I am new to Matlab. Am I doing something wrong here?

A{1} = {'aa','b','d','aa'};
A{2} = {'c','d','aa'};
A{3} = {'bb','aa','bb','aa'};

unique([A{:}])

There you go. Operators {:}

, (:)

and are []

very useful in MATLAB. It is convenient to use them.
