I have a text file having sentences.I want to edit and print each sentence in a new line .I successfully edited but find difficulty in printing

fid1=fopen('edited_sentences_program3.txt','r');
fid2=fopen('edited_sentences_program4','w');
while ~ feof(fid1)
new_line = fgetl(fid1);
a=new_line;
b=strsplit(a);
c=[b(end)  b];
c(end)=[];
 fprintf(fid2,'%s\n',c)
end
fclose(fid1);
fclose(fid2);

when I run the code ;error is

"Function is not defined for 'cell' inputs." for line fprintf(fid2,'%s\n',c)

while ~ feof(fid1)
  a = fgetl(fid1);
  b = strsplit(a);
  c = [b(end)  b(1:end-1)];
  fprintf(fid2, '%s\n', c{:})
end

I've simplified the code. To print the elements of a cell, use c{:}, which converts the cell to a comma separated list of its elements.

The description is "print each sentence in a new line". You code prints each word in a new line and moves the last word before the others. Is this intended? If not, please post an example for the input and the wanted output.

@muaz: I have no idea about what this comment means. Nobody is yelling or worrying here and which is the silly item?

You've written "I successfully edited", but your code does not split the text to sentences, but words. Therefore your posted code is confusing. "*/sx8" is a strange format for a sentence. Can you clarify this?

Oh dear! "Why yell or worry over silly items? */sx8" was an example sentence. I did not get this.

If you are OK with the contents and format of c maybe you can substitute the fprintf line by:

cellfun(@(x) fprintf(fid2, '%s\n', x), c)

This line will go element by element of the cell c and fprint it.

Maybe you want this:

Str = fileread('edited_sentences_program3.txt');
Str(ismember(Str, char([10, 13]))) = [];  % Remove line breaks.
CStr = strsplit(Str, '.');
fid = fopen('edited_sentences_program4', 'w');
fprintf(fid, '%s.\n', CStr{:});
fclose(fid);

Or even easier:

Str = fileread('edited_sentences_program3.txt');
Str(ismember(Str, char([10, 13]))) = [];  % Remove line breaks
Str = strrep(Str, '.', ['.', char(10)]);  % Insert new line breaks after each dot
fid = fopen('edited_sentences_program4', 'w');
fwrite(fid, Str, 'char');
fclose(fid);

Maybe even "?" and "!" are valid ends of a sentence. What about "..."? Where does a sentence end, if it contains direct speech?

She said, "I will be at home." and I said, "Me too!"

So please post a relevant input and what you want as output. This would make it much easier to help you to solve your problem.
