See if this does what you want:

t_d = @(t) (fix(t/100) + rem(t,100)/60)*100;                    % Anonymous Function
t_hm = 845;                                                     % Time To Be ‘Converted’
out = t_d(t_hm)                                                 % Desired Result

out =
   875

1. Use num2str
2. Lop off the last two characters with a(end-1:end)
3. str2num that
4. Divide by 60 (e.g., 45/60)
5. num2str that.
6. Put that back with the first part of the string from #2 above e.g., a = [a(1:end-1) results from #5]

There's probably a cleaner way to do this. But this should work.
