NDIM_INDICES

Name


      NDIM_INDICES

Purpose


      Indexing info for an n-dimensional table.

Category


Calling Sequence


      ndim_indices, dims, inds, s

Inputs


      dims = array of dimension sizes for table. in
      inds = array of indices into each dimension. in
        The number of elements in dims and inds must be the
        same. The first index is 0 for each dimension.

Keyword Parameters


Keywords


        ERROR=err Error flag: 0=ok.

Outputs


      s = returned information structure: out
        {nd:nd, ; number of dimensions in table.
          tot:tot, ; total cells in table.
          nc:nc, ; number of table cells completed.
          nl:nl} ; number of table cells left.

Common Blocks


Notes


      Note: For a set of indices (i1,i2,...,in) pointing to
      a cell in the n-dimensional table, the returned
      structure will indicate how many table cells there are
      before that cell in the table (nc), and how many cells
      are left including the indicated cell (nl).
      The following chart shows how the values are computed:
      Dimension Size Index #_completed
          1 n1 i1 i1 +
          2 n2 i2 i2*n1 +
          3 n3 i3 i3*n1*n2 +
          4 n4 i4 i4*n1*n2*n3 +
          ... ... ... ...
      Sum the last column over all the dimensions in the table
      to get the number of cells completed.
