Are you just trying to double number in an array and copying it to another array?

Code:
DMGLIST=(1 2 3 4)
for (( i = 0 ; i < "${#DMGLIST[@]}"; i++ )) 
do
    DMGLIST2[$i]=$((${DMGLIST[$i]}*2))
    echo "${DMGLIST2[$i]}";
done

dlar2v.f(3)							      LAPACK							       dlar2v.f(3)

NAME

       dlar2v.f -

SYNOPSIS

   Functions/Subroutines
       subroutine dlar2v (N, X, Y, Z, INCX, C, S, INCC)
	   DLAR2V

Function/Subroutine Documentation
   subroutine dlar2v (integerN, double precision, dimension( * )X, double precision, dimension( * )Y, double precision, dimension( * )Z,
       integerINCX, double precision, dimension( * )C, double precision, dimension( * )S, integerINCC)
       DLAR2V

       Purpose:

	    DLAR2V applies a vector of real plane rotations from both sides to
	    a sequence of 2-by-2 real symmetric matrices, defined by the elements
	    of the vectors x, y and z. For i = 1,2,...,n

	       ( x(i)  z(i) ) := (  c(i)  s(i) ) ( x(i)  z(i) ) ( c(i) -s(i) )
	       ( z(i)  y(i) )	 ( -s(i)  c(i) ) ( z(i)  y(i) ) ( s(i)	c(i) )

       Parameters:
	   N

		     N is INTEGER
		     The number of plane rotations to be applied.

	   X

		     X is DOUBLE PRECISION array,
				    dimension (1+(N-1)*INCX)
		     The vector x.

	   Y

		     Y is DOUBLE PRECISION array,
				    dimension (1+(N-1)*INCX)
		     The vector y.

	   Z

		     Z is DOUBLE PRECISION array,
				    dimension (1+(N-1)*INCX)
		     The vector z.

	   INCX

		     INCX is INTEGER
		     The increment between elements of X, Y and Z. INCX > 0.

	   C

		     C is DOUBLE PRECISION array, dimension (1+(N-1)*INCC)
		     The cosines of the plane rotations.

	   S

		     S is DOUBLE PRECISION array, dimension (1+(N-1)*INCC)
		     The sines of the plane rotations.

	   INCC

		     INCC is INTEGER
		     The increment between elements of C and S. INCC > 0.
