UD01MZ

Printing a real matrix (complex case)

Purpose

  To print an M-by-N real matrix A row by row. The elements of A
  are output to 7 significant figures.

      SUBROUTINE UD01MZ( M, N, L, NOUT, A, LDA, TEXT, INFO )
C     .. Scalar Arguments ..
      INTEGER           INFO, L, LDA, M, N, NOUT
      CHARACTER*(*)     TEXT
C     .. Array Arguments ..
      COMPLEX*16        A(LDA,*)

Input/Output Parameters

  M       (input) INTEGER
          The number of rows of matrix A to be printed.  M >= 1.

  N       (input) INTEGER
          The number of columns of matrix A to be printed.  N >= 1.

  L       (input) INTEGER
          The number of elements of matrix A to be printed per line.
          1 <= L <= 3.

  NOUT    (input) INTEGER
          The output channel to which the results are sent.
          NOUT >= 0.

  A       (input) COMPLEX*16 array, dimension (LDA,N)
          The leading M-by-N part of this array must contain the
          matrix to be printed.

  LDA     INTEGER
          The leading dimension of array A.  LDA >= M.

  TEXT    (input) CHARACTER*72.
          Title caption of the matrix to be printed (up to a
          maximum of 72 characters). For example, TEXT = 'Matrix A'.

  INFO    INTEGER
          = 0:  successful exit;
          < 0:  if INFO = -i, the i-th argument had an illegal
                value.

  The routine first prints the contents of TEXT as a title, followed
  by the elements of the matrix A such that

  (i)  if N <= L, the leading M-by-N part is printed;
  (ii) if N = k*L + p (where k,p > 0), then k M-by-L blocks of
       consecutive columns of A are printed one after another
       followed by one M-by-p block containing the last p columns
       of A.

  Row numbers are printed on the left of each row and a column
  number appears on top of each complex column.
  The routine uses 2 + (k + 1)*(m + 1) lines and 7 + 32*c positions
  per line where c is the actual number of columns, (i.e. c = L
  or c = p).
