MATLAB: Cell Array to .txt file

arraycell arrayMATLAB

Hi,
I am working on importing a .txt file, altering some of the text inside of it then, writing it to a new .txt file.
I import the .txt file as a cell array, perform my math then, attempt to write it back to a new .txt file.
The text I am attempting to alter is CNC code. Therefore, at the end of each line I need a semi-colon.
This is my code:
   fid = fopen('newpartcode.txt','w');
for i=1:m
   fprintf(fid,'%s',pcn{i,:});
   fprintf(fid,';');
   fprintf(fid,'\n');
end
fclose(fid);
The results I am getting look like:
%;O0000;G20;G0G17G40G49G80G90;T1M6;
When I need it to create a new line after each semi-colon
Any help is welcome

Try
    str = '%;O0000;G20;G0G17G40G49G80G90;T1M6;';
    cac = regexp( str, ';', 'split' );
    str = sprintf( '%s;\n', cac{1:end-1} );
    str
it returns
    %;
    O0000;
    G20;
    G0G17G40G49G80G90;
    T1M6;
or better replace
   fprintf(fid,'%s',pcn{i,:});
   fprintf(fid,';');
   fprintf(fid,'\n');
by
    fprintf(fid,'%s;\n',pcn{i,:});
Is
    %;O0000;G20;G0G17G40G49G80G90;T1M6;
how it looks in Notepad? You might want to replace '\n' by '\n\r' - mistake: it should be \r\n.
