I'd recommend you follow the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F because your method is not very robust. I prefer sprintf(). If you're not going to use, or can't use, dir() to get a listing of what files are there, then at least you should use exist() so you don't throw an exception that aborts your loop when the file is not found. That is what people do when they write robust code.
for k = 1 : 100 % Use k, not i (the imaginary variable)
baseFileName = sprintf('filename%d', k);
% Prepend the folder where the files live.
% If it's the current folder, then you can use folder = pwd.
fullFileName = fullfile(folder, baseFileName);
if exist(fullFileName, 'file')
% If the file exists, delete it.
delete(fullFileName);
end
end
but again, see the FAQ for better code examples than that.

If you put the extension on the baseFileName it will the get included correctly in the fullFileName.
%d is a placeholder for an integer which gets replaced by the value of k each time round the loop (look at formatSpec in the help for sprintf for other options here if you are interested in general, but %d is the correct one for this case)

Try using this !
for i=1:100
delete(strcat('filename',num2str(i)))
end
Cheers !
