function Discriminant (a)
a = input('Enter the value of a: ');
b = a*2
fprintf('The value of b is: %i', b)
end
This is an example of the code I am going to use. I want there to be a prompt for a user to enter a value of a, and in turn, my function will use that value of a in the formula, and print the value of b.

Regardless of the fact that you are using functions, have a look at your code:
function Discriminant (a)
a = input('Enter the value of a: ');
You define a somehow (as a function input... but really it does not matter how, all that matters is that it is defined because this basic principal applies to all variables all of the time). The you redefine a to be something else (using INPUT, but again it does not really matter how you do this).
If you want to use the original a that you defined, then don't redefine a to be something else.
INPUT... needs to be unlearned one day.
