Merge multiple cell arrays

My cell array S <1x4cell> contains 4 cell arrays (<108x1cell>,<106x1cell>,<111x1cell>,<115x1cell>), each of which contains a list of roughly a hundred file paths.

I want to merge them in order to get one single cell with all my paths. Is there a single function to do that?

Concatenate your cell arrays and use unique:

%// example data
A ={'a';
     'b';
     'c';
     'd'};
B = {'a';
     'e';
     'f'};
C = {'g';
     'a';
     'c'};

%// merge cells
merged = [A(:); B(:); C(:)]
%// or
merged = cat(1, A(:), B(:), C(:))

%// remove duplicates
filtered = unique(merged)

or assumiming you already have the cell array S = merged, do the following:

S = { A, B, C }

%// remove duplicates
filtered = unique(cat(1,S{:}))
