 as follows:
          = 'N':  op(K) = K    (No transpose);
          = 'C':  op(K) = K**H (Conjugate transpose).

<PRE>
  N       (input) INTEGER
          The order of the matrix A and the number of columns of
          the matrix op(B).  N &gt;= 0.

  M       (input) INTEGER
          The number of rows of the matrix op(B).  M &gt;= 0.
          If M = 0, A is unchanged on exit, and Q and W are not set.

  A       (input/output) COMPLEX*16 array, dimension (LDA,N)
