<PRE>
  To store by skew-symmetry the upper or lower triangle of a
  skew-symmetric matrix, given the other triangle. The diagonal
  entries are set to zero.

<B>Mode Parameters</B>
<PRE>
  UPLO    CHARACTER*1
          Specifies which part of the matrix is given as follows:
          = 'U':  Upper triangular part;
          = 'L':  Lower triangular part.
          For all other values, the array A is not referenced.

</PRE>
<B>Input/Output Parameters</B>
<PRE>
  N       (input) INTEGER
          The order of the matrix A.  N &gt;= 0.

  A       (input/output) DOUBLE PRECISION array, dimension (LDA,N)
          On entry, the leading N-by-N upper triangular part
          (if UPLO = 'U'), or lower triangular part (if UPLO = 'L'),
          of this array must contain the corresponding upper or
          lower triangle of the skew-symmetric matrix A.
          On exit, the leading N-by-N part of this array contains
          the skew-symmetric matrix A with all elements stored.

  LDA     INTEGER
          The leading dimension of the array A.  LDA &gt;= max(1,N).
