Cannot support cell arrays containing cell arrays or objects.

I created a cell Array like this

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

now i wanna find the 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'm fairly new to matlab. Am I doing something wrong here?

You can use comma-separated list expansion here:

B = [A{:}]

Hi,

the aim of cell2mat is to convert a cell that contains numbers into an array (matrix).

your cell contains strings, so it can't work.
