Deal With the Input and Output Arguments
- Use nargin and nargout to determine the number of input and output arguments.
- Use the nargchk and nargoutchk to verify the number of input and output arguments.
- Example (find the minimum number)
function [x,y,z] = myarg(a, b, c, d)
disp(nargchk(2, 4, nargin)) % Allow 2 to 4 inputs
disp(nargoutchk(0,2,nargout)) % Allow 0 to 2 ouputs
x = a;
if (a > b)
x = b;
end
if nargin == 4
y = c;
if (c > d)
y = d;
end
z = x;
if x > y
z = y;
end
else
y = x;
z = x;
end
