How do I generate random numbers within a certain range a and b but excluding a specific number within this range, let's call this number c?

so for example the function has to be randint_reject(a,b,c) where it generates random numbers from a and b but excludes the value of c. if I have a = 2, b = 6, and c = 4. I would generate numbers between 2 and 6 excluding the number 5. This is what I have so far:

function f = ranInt_reject(a,b,c)

 randInt_reject = (b-a)*rand + a; 
    f = randInt_reject;
    if f == c
      f = c + 1;
    else
      f = randInt_reject;
    end
end

Any help will be highly appreciated, thanks!

In what way does this request differ from your request #106041?

This one has the mysterious "Monty Hall Problem" tag added. I have no idea why, but I attach my Monty Hall program just for fun.

It doesn't, I just figured I was being a little ambiguous on the previous one and decided to add some more details, and the reason why I added the monty hall tag is because this is one of the prerequisites I need in order to solve that problem.
