error(nargoutchk(2, 4, nargout, 'struct'))
nargoutchk
If nargoutchk detects no error, it returns an empty string or structure. When
nargoutchk is used with the error function, as shown here, this empty string
or structure is passed as an input to error. When error receives an empty
string or structure, it simply returns and no error is generated.
Examples You can use nargoutchk to determine if an M-file has been called with the
correct number of output arguments. This example uses nargout to return the
number of output arguments specified when the function was called. The
function is designed to be called with one, two, or three output arguments. If
called with no arguments or more than three arguments, nargoutchk returns
an error message:
function [s, varargout] = mysize(x)
msg = nargoutchk(1, 3, nargout);
if isempty(msg)
nout = max(nargout, 1) - 1;
s = size(x);
for k = 1:nout, varargout(k) = {s(k)}; end
else
disp(msg)
end
