How would I write a function that uses 2 numbers as inputs and displays the smallest of the 2 numbers by printing "The smallest number is X" (x would be the smaller number in this case).
I have Matlab r2016b , but there seems to be older methods of doing this. I'm looking to do it in a more modern way.
Thanks for looking!

You can use oprations like >/ < to find which is smaller number. You can use fprintf to print the required statement. Read about fprintf, min and max. As this is a home work, you have to work on your own.

Like this?
compare = @(a,b) min(a,b);
sprintf('The smallest number is %d',compare(2,3))
Or like this?
function x = compare(a,b)
sprintf('The smallest number is %d', min(a,b))
end

Just use function
MinValue = min(a,b)
That is all what you need.

a=1;
b=2;
if min(a,b)
fprintf("hello");

The code you wrote does not actually work. TRY IT!!!!!! Don't just post something incorrect without even bothering to test your own code. What do you think the test
if min(a,b)
will do?

a = 1;
b = 0;
if min(a,b)
fprintf("hello");
else
fprintf("odd, where is my expected output?\n")
end
odd, where is my expected output?
