代码
function varargout=definedAndVariableNumInputs(X,Y,varargin)
disp("Total number of input arguments: " + nargin)
formatSpec = "Size of varargin cell array: %dx%d";
str = compose(formatSpec,size(varargin));
disp(str)
if nargout==1
varargout={X};
elseif nargout==2
varargout={X,Y};
else
error('错误');
end
end
输出
>> a=definedAndVariableNumInputs(7,pi,rand(4),datetime('now'),'hello')
Total number of input arguments: 5
Size of varargin cell array: 1x3
a =
7
>> [a,b]=definedAndVariableNumInputs(7,pi,rand(4),datetime('now'),'hello')
Total number of input arguments: 5
Size of varargin cell array: 1x3
a =
7
b =
3.1416
>> [a,b,c]=definedAndVariableNumInputs(7,pi,rand(4),datetime('now'),'hello')
Total number of input arguments: 5
Size of varargin cell array: 1x3
错误使用 definedAndVariableNumInputs (line 13)
