Execute a function till she reproduces twice in a row the same result

I wrote a (working) function. Now i need to execute the function till she reproduces two times the same result. How do i do this?

I would use a while loop. Something like this maybe: (If your function produces a 'new' value every time you call it.)

 value1 = myfunctionvalue()
 error = 1;
 while error ~= 0
    value2 = myfunctionvalue();
    error = value2 - value1
    value1 = value2
 end

Although, really you should probably have some tolerance on the while loop (error<tolerance). If the subsequent calls don't match exactly, then the above approach could get stuck.
