for i=1:nargin
nargin is the number of all inputs. For Untitled(a,varargin) thenumber of inputs is 1 larger than the size of varargin.
Try:
for i = 1:numel(varargin)
% or
for i = 1:nargin - 1
Hint: Omit the "i=i+1", which is useless. The loop counter is increased by the for command. It does not produce an error here, because i is not used after this line, but it is confusing. See
for k = 1:5
fprintf('k = %d\n', k);
k = k + 1000;
fprintf('modificed k = %d\n', k);
end
