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.

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)

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)
