This is a correct solution - alas using a function handle, not an m-file

Test	Status	Code Input and Output
1	Fail	[q,r] = swapInputs(5,10); assert(isequal(q,10)); assert(isequal(r,5)); Undefined function 'swapInputs' for input arguments of type 'double'. Error in Test1 (line 1) [q,r] = swapInputs(5,10);
2	Fail	[q,r] = swapInputs(magic(3), 'hello, world'); assert(isequal(q,'hello, world')); assert(isequal(r,magic(3))); Undefined function 'swapInputs' for input arguments of type 'double'. Error in Test2 (line 1) [q,r] = swapInputs(magic(3), 'hello, world');
3	Fail	[q,r] = swapInputs({}, NaN); assert(isnan(q)); assert(iscell(r) && isempty(r)); Undefined function 'swapInputs' for input arguments of type 'cell'. Error in Test3 (line 1) [q,r] = swapInputs({}, NaN);
