-* Purpose
-* =======
-*
-* ZLANGB returns the value of the one norm, or the Frobenius norm, or
-* the infinity norm, or the element of largest absolute value of an
-* n by n band matrix A, with kl sub-diagonals and ku super-diagonals.

-* Description
-* ===========
-*
-* ZLANGB returns the value
-*
-* ZLANGB = ( max(abs(A(i,j))), NORM = 'M' or 'm'

-* ( norm1(A), NORM = '1', 'O' or 'o'
-* (
-* ( normI(A), NORM = 'I' or 'i'
-* (
-* ( normF(A), NORM = 'F', 'f', 'E' or 'e'
-*
-* where norm1 denotes the one norm of a matrix (maximum column sum),
-* normI denotes the infinity norm of a matrix (maximum row sum) and
-* normF denotes the Frobenius norm of a matrix (square root of sum of
-* squares). Note that max(abs(A(i,j))) is not a consistent matrix norm.
-*
-* Arguments
-* =========
-*
-* NORM (input) CHARACTER*1
-* Specifies the value to be returned in ZLANGB as described
-* above.
-*
-* N (input) INTEGER
-* The order of the matrix A. N >= 0. When N = 0, ZLANGB is
-* set to zero.

-* The number of sub-diagonals of the matrix A. KL >= 0.
-*
-* KU (input) INTEGER
-* The number of super-diagonals of the matrix A. KU >= 0.
-*
-* AB (input) COMPLEX*16 array, dimension (LDAB,N)
-* The band matrix A, stored in rows 1 to KL+KU+1. The j-th
-* column of A is stored in the j-th column of the array AB as
-* follows:
-* AB(ku+1+i-j,j) = A(i,j) for max(1,j-ku)<=i<=min(n,j+kl).
-*
-* LDAB (input) INTEGER
-* The leading dimension of the array AB. LDAB >= KL+KU+1.
-*
-* WORK (workspace) DOUBLE PRECISION array, dimension (MAX(1,LWORK)),
