How can I write data to a text file using the symbol '/' in the end?

As the header implies i need to write data from a matrix to a text file and in the end of each line there must be the symbol '/'. Example of the needed output:
1 2 /
1 2 /
1 2 /
I have already written the script and used dlmwrite to create the text file. If it is possible i would like to keep dlmwrite. Any help will be appreciated. Thanks in advance.

"keep dlmwrite" That's not possible - AFAIK
Doc says: dlmwrite(filename,M) writes numeric data in array M to an ASCII format file.
This is one way
>> sprintf('%1d %1d %1c', 1,2,'/')
ans =
1 2 /
>>
Replace sprintf by fprintf

In order to use dlmwrite for this purpose, you will need to convert all of your data to a cell array in which each entry is an individual character, including entries for any separating spaces. Then you need to dlmwrite() specifying '' (the empty string) as the delimiter, and specify the precision parameter:
For example for the above output you would need something like
data = [1, 2; 1, 2; 1, 2];
temp = num2cell( num2str(data, '%d %d /'));
dlmwrite('TheFilename.txt', temp, '', 'Precision', '%s')
