Thread Subject: writing functions

i have to creat a function of


f(x) ={ 3-|2x| if|x|<=1.5
           0 if x<-1
         2x-2 if x >1


this is what i did but not why it is not working

function out = myfun1(in)
if in<= abs(1.5)
    out =3-abs(2x);
else if in <-1
     out=0;
    else
        2x-2
    end

  Your trouble is principally caused by the poor function definition. If for example x is equal to 1.25 it satisfies both the requirement that abs(x)<1.5 and that x>1, or if x = -1.25 it satisfies both abs(x)<1.5 and x<-1. What is 'out' supposed to be in these cases? You had better straighten that out before you attempt to write code for it.
