invalid array access in Output Function

[MatlabCoder98]

i wrote a function to give a vector [ z1...z10] of zigzag index of any forex currency in function output.

but it show error in compliation.

// int ExtDepth=12;
   int bigshift=1;
   int ExtDeviation=5;
   int ExtBackstep=3;
   int counted_bars=IndicatorCounted();
   int izig=0,MaxZig=8;
   double Ext,ZigArray[];
   ArrayResize(ZigArray,MaxZig);

   if(counted_bars<0)
      counted_bars=0;
   if(counted_bars>0)
     {
      counted_bars--;
      while(izig<MaxZig)
        {
         Ext=iCustom(symbolName,ZTimeframe,"ZigZag",ExtDepth,ExtDeviation,ExtBackstep,0,bigshift);
         bigshift++;
         if(100000*Ext>1)
           {
            ZigArray[izig]=Ext;
            izig++;

           }
        }
     }
   return (ZigArray);

'ZigArray' - invalid array access Ztest.mq4  93 12

that   ZigArray is my required vector with 8 elements.

please help me to solve it.

god bless you

You can not return an array. Pass the array in by reference.
