Cell Array to .txt file
显示 更早的评论
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.

fid = fopen('newpartcode.txt','w');
pcnT = pcn.';
fprintf(fid,'%s;\n', pcn{:});
fclose(fid);
Now there are linebreaks behind each semicolon, but you cannot see them, when the file is opened by the childish NotePad ("Editor" in German). This program insists on the old DOS linebreaks '\r\n' since Windows 3.1. All other editors can handle the \n linebreaks correctly.
In your case it matters, which kind of linebreaks the CNC machine expects. So please find out this important detail and install NotePad++ or use WordPad as standard viewer for txt files.

There is no such setting in NotePad. Why do you use NotePad? Matlabs editor is better. The free NotePad++ is a good replacement for NotePad.
