Using two functions in a loop

Hi,

I want to use two functions in a loop in a way that the second function is activated only when the first function returns an error message. How can I do that?

iter=1;
for i=1:iter
    try
        fun1(3,8)
    catch 
        fun2(4,6)
    end 
end 

function z=fun1(a,b)
z=a.b
end 

function z1=fun2(c,d)
z1=c+d;
end
