How to recall the answer of an if statement in matlab?

I am writing a function, which is suppose to give the result of the following if loop:

s=some scalar
i=some scalar ; 
    if  y(s,i)==L 
        U(1,i)==0 
    else disp('Never binding') ;
    end   

How can I store the "answer" so that the name given to the answer is the output of the function?

for example: ans=R and function R=myfunction(i,s)

Is this possible?

Thank you
