Error: Not enough input argument (line 6)
显示 更早的评论
Why do I get this error message when running following script?
function outtype = findargtype (inputarg)
% findargtype determines whether the input
% argument is a scalar,vector, or matrix
% format of call: findargtype(inputArgument)
% Returns a string
[r c] = size (inputarg) ;
if r== 1 && c== 1
outtype='scalar';
elseif r== 1 || c== 1
outtype='vector';
else
outtype='matrix';
end
end

How are you calling your function findargtype from your main script? What are you giving it for inputarg as an argument?

Your code does not react consistently to empty inputs. The [] construct is 0 by 0 and so would show up as 'matrix' in your tests, but zeros(0,1) would show up as vector.
Please also try this test:
[r c] = size(zeros(0,1,2))
and
[r c] = size(zeros(1,0,2))
size() does not do what you think it does.

The error is not in the function, but in the way you called it. You called it with no input arguments.
