-* Purpose
-* =======
-*
-* ZGECON estimates the reciprocal of the condition number of a general
-* complex matrix A, in either the 1-norm or the infinity-norm, using
-* the LU factorization computed by ZGETRF.
-*
-* An estimate is obtained for norm(inv(A)), and the reciprocal of the
-* condition number is computed as
-* RCOND = 1 / ( norm(A) * norm(inv(A)) ).

-* Arguments
-* =========
-*
-* NORM (input) CHARACTER*1
-* Specifies whether the 1-norm condition number or the
-* infinity-norm condition number is required:
-* = '1' or 'O': 1-norm;
-* = 'I': Infinity-norm.
-*
-* N (input) INTEGER
-* The order of the matrix A. N >= 0.
-*
-* A (input) COMPLEX*16 array, dimension (LDA,N)
-* The factors L and U from the factorization A = P*L*U
-* as computed by ZGETRF.
-*
-* LDA (input) INTEGER
-* The leading dimension of the array A. LDA >= max(1,N).
-*
-* ANORM (input) DOUBLE PRECISION
-* If NORM = '1' or 'O', the 1-norm of the original matrix A.
-* If NORM = 'I', the infinity-norm of the original matrix A.
-*
-* RCOND (output) DOUBLE PRECISION
-* The reciprocal of the condition number of the matrix A,
-* computed as RCOND = 1/(norm(A) * norm(inv(A))).
