How to properly use varargout and nargout?

Hi! I need to calculate the bits and nibbles from an input of bytes. If the functions expects two outputs, the it will calcualtion the nibles. But of not, it will calculate the bits. My code looks like this:

function [varargout] = bytes2bits(bytes)
 % write your solution here:
if nargout == 2
    varargout{1} = bytes./8;
    varargout{2} = bytes./32;
else
    varargout{1} = bytes./8;
end
end

and the error that I am getting (from the eudcational platform) is:

Function failed when calculating bits with one output.

You neglected to show us the code line that called the function and the entire error message text in context...

No problems here

>> bytes2bits( 64 )
ans =
     8
>> [a1,a2] = bytes2bits( 64 );
>> [a1] = bytes2bits( 64 );
>>

The code seems correct.

However, you can try this

if nargout == 2
    varargout{1} = bytes./8;
    varargout{2} = bytes./32;
elseif nargout == 1
    varargout{1} = bytes./8;
end
