e order
          of the matrix Z.  N &gt;= 0.

  RANKE   (input) INTEGER
          The rank of the matrix E in column echelon form.
          RANKE &gt;= 0.

  A       (input/output) DOUBLE PRECISION array, dimension (LDA,N)
          On entry, the leading M-by-N part of this array must
          contain the matrix to be row compressed.
          On exit, the leading M-by-N part of this array contains
          the matrix that has been row compressed while keeping
          matrix E in column echelon form.
