2379 Write a Matlab function CHECKINPUT that accepts (up to) four inputs and returns the number of input arguments being passed to that function as a single variable NumArg. Assume the number of inputs passed will be four or less. % Function name: CHECKINPUT % Purpose = returns the number of input arguments being passed to that function % Do not upload test cases. function numarg = CHECKINPUT(a,b,c) switch nargin case c numarg = c; case b numarg = b; case a numarg = a; otherwise numarg = 0; end end
