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.

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
