Please help me test to see if a string is divisible by a number using tk (token).

I am trying to write a script to see if a text file 'example.txt'

67 33 60
-9 6
89 99 66

is divisible by aa given number. I've gotten this script I have been working on:

ifh=fopen(fname,'r');   %open the file for reading
[tk,ln]=strtok(ln);
if mod(tk/num==0)
end
fprintf(ofh, '%s ', tk);

but I'm not sure how to get the test each token to see if it is divisible. I was told the str2num and num2str functions would be useful. I do not fully understand how to use the tk function.

"but I'm not sure how to get the test each token to see if it is divisible."

I showed you that more than twelve hours ago, in your previousl (almost) identical question. Please do not repeatedly post the same question.

You did not show me using the token function, that is why I asked this again. Thanks for the help but I can not use the script you provided. The functions you used have not been taught in my class so I cannot use them.
