How to join the subelements of a cell?

I am trying to express all sentences in one cell with string subelements.

 s='I am George. John is there? Ana is around! Are you mad?'

[y,matches] = strsplit(s,{'.','?','!'})
for i = 1:length(matches)
y{i}=[y{i},matches{i}]
end

y=y(~cellfun('isempty',y))

Don't think you finished your question (because I'm not sure what it is). If you're trying to rejoin all the sub-strings in y, see my answer below.

Answer 1

[Matt J]

s=[y{:}]

[GEORGIOS BEKAS]

isa(s,'cell') =0

[Matt J]

 s={[y{:}]}

the problem is that the strings are not separate. C[1,1] = 'I am George.' 'John is there?' 'Ana is around!' 'Are you mad?'

What does are not separate mean?

Please use valid matlab syntax. Otherwise it doesn't help in explaining at all.

seperate strings into one cell subelement.

This is what I receive when I run the code you posted followed by Matt's suggestion.

s = 'I am George. John is there? Ana is around! Are you mad?'
[y,matches] = strsplit(s,{'.','?','!'})
for i = 1:length(matches)
y{i}=[y{i},matches{i}]
end
y=y(~cellfun('isempty',y))
s2 = [y{:}]
whos s2

s2 =

      'I am George. John is there? Ana is around! Are you mad?'

Name      Size            Bytes  Class    Attributes

s2        1x55              110  char

What exactly do you need/want/expect s2 to be for this example? Be specific about the type and size you expect s2 to be and the contents you expect s2 to contain.

To join elements of the cell array, y, you can use:

y = cell2mat(y);

or

y = {cell2mat(y)};

for a cell array.

To more generally achieve what you're trying to do, you can use regular expressions:

expression = '(?<=\W)\s'; % Expression to find white space following punctuation
strsplit(s,expression,'delimitertype','regularexpression'); % split string around result of regexp

the problem is that the strings are not separate. C[1,1] = 'I am George.' 'John is there?' 'Ana is around!' 'Are you mad?'

[Domanic]

How about:

expression = '(?<=\W)\s';
y = strsplit(s,expression,'delimitertype','regularexpression');
y = {cell2struct(y,'substrings')};

where the strings are accessed as:

y{1}.substrings

or

y{1}.substrings(1)

not sure why you'd want this, though.
