array is not allowed as input

[tinivini]

Hi .I want to define an array like this :

input double fibo[4]={0,0.236,0.382,0.618};

when use in optimization i want start this numbers from begin to end .

but i see error "array is not allowed as input "

also i try with enum , but also enum only accept int number not double

enum enum_fibo
  {
   fibo_0_236=0.236,
   fibo_0_382=0.382,
   fibo_0_618=0.618,
   fibo_0_786=0.786,
   fibo_1=1,
   fibo_1_618=1.618,
  };

input enum_fibo fibo_0_236;

error : "'=' - constant expression is not integral"

please guide me .

Use integers in enum, and then cast them to type 'double'
