How to display the vector in this question?

Write a function func that will receive one input argument x.

If x is a scalar, the function will return its square root, provided x is non-negative.

If x<0, print an error message: “Error Message: You entered a negative number”.

If x is a vector, the function returns the sum of its components.

If x is a square matrix, the function returns its symmetric part.

If x is a rectangular matrix, the function returns the product of its number of rows and number of columns.

What if x is a square matrix but not symmetric ?

The question does not ask you to display anything, only to return particular values.

Right now I got these typed:

m = input('Enter m: ');

n = randi([1,10]);

%since the question only receive ONE input, the second one can be a random integer

func = m:n

x = func

if m==1 && n==1 % x is scalar

    func = sqrt(func);

elseif m<0

    disp('Error Message: You entered a negative number')

elseif m==1 && n>1 m>1 && n==1 % x is a vector

    func = sum(x);

elseif m==n % x is square matrix

    func = flipud(flipplr(x));

else % x is rectangular matrix

    numel(x)

end

I believe I did something wrong with the func itself (bold text part), but I don't know how to fix it.
