function creating new vector

i need to create a function that has an input of vector with 10 elements and it creates a new vector containing only elements between 0 and 1 times 2 minus 1 i cant figure out what i did wrong

function likelehood=like(x) counter=0; w=zeros(1,10); for i=1:10 if 0<x(1,i)<1; counter=counter+1; w(1,counter)=(2*x(1,i)-1)+w(1,i); end likelehood=w; end

Answer 1

 if 0<x(1,i)<1

should be

 if x(1,i)>0 && x(1,i)<1

hi, try this function :

 function y=likelihood(x) 

 T=x((x>0)&(x<1));
 y=2*T-1;
