  First, the elements P(i,j,k) with 1 &lt;= i &lt;= MP, 1 &lt;= j &lt;= NP and
  1 &lt;= k &lt;= DP + 1 are set to zero. Next the nonzero (polynomial)
  elements are read from the input file NIN. Each nonzero element is
  given by the values i, j, d, P(i,j,k), k = 1, ..., d+1, where d is
  the degree and P(i,j,k) is the coefficient of s**(k-1) in the
  (i,j)-th element of P(s), i.e., let
