If your char class variable is named str:

 fid = fopen( 'myFile.txt', 'w' ) ;
 fprintf( fid, strrep( str, ';', '\n' )) ;            % Or '\r\n' if you want 
 fclose( fid ) ;                                      % to be Windows-friendly.

Thank but it only remove the ; signed and does do the newline

C =  '12 14; 13 56; 89 45; 892 45; 89 425; 189 425; 892 15'  
fid = fopen( 'd:/myFile.txt', 'w' )  
 fprintf( fid, strrep( C, ';', '\n' )) ;
 fclose( fid ) ;

It's probably because you opened the file using the notepad under Windows, which needs '\r\n' to interpret newlines correctly. Try with the update that I mention in the comment:

 fprintf( fid, strrep( str, ';', '\r\n' )) ;

n=5
str=regexp(sprintf('X%d Y%d ',repmat(1:n,2)),'X\d\s+Y\d','match')
fid=fopen('file.txt','w')
fprintf(fid,'%s\r\n',str{:})
fclose(fid)

Thanks. I am new in regexp.

Can you please show me how to implement your code with this char

C =  '12 14; 13 56; 89 45; 892 45; 89 425; 189 425; 892 15'

C =  '12 14; 13 56; 89 45; 892 45; 89 425; 189 425; 892 15'  
str=regexp(C,';','split')
fid=fopen('file.txt','w')
fprintf(fid,'%s\r\n',str{:})
fclose(fid)
