*
*  Routine:    ZMOUT
*
*  Purpose:    Complex*16 matrix output routine.
*
*  Usage:      CALL ZMOUT (LOUT, M, N, A, LDA, IDIGIT, IFMT)
*
*  Arguments
*     M      - Number of rows of A.  (Input)
*     N      - Number of columns of A.  (Input)
*     A      - Complex*16 M by N matrix to be printed.  (Input)
*     LDA    - Leading dimension of A exactly as specified in the
*              dimension statement of the calling program.  (Input)
*     IFMT   - Format to be used in printing matrix A.  (Input)
*     IDIGIT - Print up to IABS(IDIGIT) decimal digits per number.  (In)
*              If IDIGIT .LT. 0, printing is done with 72 columns.
*              If IDIGIT .GT. 0, printing is done with 132 columns.
