printing full stop in next line

fid1=fopen('prompts2','r');
fid2=fopen('prompts3trialtimitsmall','w');
while ~ feof(fid1)
    new_line = fgetl(fid1);
    a=new_line;
    b=strsplit(a);
    c=[b(end)  b];
    c(end)=[];
    c=c;
    fprintf(fid2, '%s\n', c {:})
end
fclose(fid1);
fclose(fid2);

my sentences in prompts2 are like this Alfalfa is healthy for you. */sx21 sentences in output file is

*/sx21
Alfalfa
is
healthy
for
you.

I want

*/sx21
Alfalfa
is
healthy
for
you
.

i.e. last full stop to print in next line I have tried converting z= char(c(end)) and then printing but not succed.

Replace:

fprintf(fid2, '%s\n', c {:})

by

str = sprintf('%s\n', c {:});
str = strrep(str, '.', [char(10), '.']);  % [EDITED, typo fixed]
fprintf(fid2, '%s', str);

when I run above I got an error

Error using strrep
Not enough input arguments.

Error in trial_timitsmall (line 15)
str = strrep('.', [char(10), '.']);

also I have tried many different options with strrep but not worked

[libra]

completed myself by simple programming

b=strsplit(a);c=[b(end)  b];
c=cat(2,b(end),b);
c(end)=[];
c=c(1:end);
k=c(end);
l=char(c(end));
l(end)=[];
l=l
d=vertcat(c','.')
g=d(end-1);
h=char(g);
h(end)=[];
h=h;
s=d(end-1);
j=strrep(d,s,h)
fprintf(fid2, '%s\n', j{:})

by changing in above code

Yes, I had a typo in my code. Replace

str = strrep('.', [char(10), '.']);

by

str = strrep(str, '.', [char(10), '.']);

Using the curly braces to access a cell element is more efficient than creating a scalar cell at first and converting it by char:

% l=char(c(end))
l = c{end};  % Much better and nicer

This is not meaningful:

h=h;
% or
c=c;

This is simply a waste of time and confuses the readers. This is cluttering also:

    new_line = fgetl(fid1);
    a=new_line;

What about:

a = fgetl(fid1)

?

This does the same thing twice, so omit one of the lines:

c=[b(end)  b];
c=cat(2,b(end),b);

This is not used anywhere, to better remove it:

k=c(end);

Finally let me summary my suggestion with your original (much clearer) code:

fid1 = fopen('prompts2','r');
fid2 = fopen('prompts3trialtimitsmall','w');
while ~ feof(fid1)
    a   = fgetl(fid1);
    b   = strsplit(a);
    c   = [b(end), b(1:end-1)];
    str = sprintf('%s\n', c{:});
    str = strrep(str, '.', [char(10), '.']);
    fwrite(fid2, str, 'char');  % Faster than FPRINTF
end
fclose(fid1);
fclose(fid2);
