You have to ask it specifically for as many outputs as you want it to return. By default, if you only ask it for one, it will only return the first. This call returns all of them:
a = 2;
b = 5;
c = 10;
[j,k,group]=quadratic_roots(a,b,c)
Also, I would change:
group='non-equal complex valued roots'
to:
group='complex-conjugate roots'

That is already being dealt with in your question http://uk.mathworks.com/matlabcentral/answers/258976-i-m-having-problems-creating-a-program-that-prompts-a-user-to-guess-the-colour
