14f2011baa Add MEX auto-build support for function 'mex_generate_coarsegrid'. 2010-08-30 21:43:39 +00:00
Bård Skaflestad
e0c6e24ab7 Correct a number of small, but crucial, mistakes: 
- Initialise new neighbours to INT_MIN rather than -1.  The latter
      is a valid block (the outside) and it is better to properly
      distinguish unset values from boundary blocks.

    - Ensure NULL-initialisation of a block's neighbour structure when
      this structure has just been allocated.

    - Adjust bin-search algorithm to support i==nneigh (target larger
      than all existing neighbouring blocks).

    - This means that if i==nneigh, then we must take precaution so as
      not to reference any invalid table elements.  However, an
      explicit check for i<nneigh means that the semantics of the
      memmove() statement becomes more transparent.

    - Finally, we must properly assign the 'nblocks' and 'nfaces'
      fields of the struct coarse_topology before returning to caller.

4b7a67de8e Silence compiler by adding prototype for dfs() (i.e., #include 
"dfs.h").  Also, don't require build(er|system) to always #define
  the preprocessing symbol "TEST" (to a zero or non-zero value).

66369d49ff Correct a supremely embarrassing typo: When counting the number of 
cell-to-cell connections (i.e., when calling count_block_conns()),
  inspect the pointer array (pc2c) rather than the cell array itself
  (c2c).  Clue-by-four supplied by gdb(1).

  Move self connection handling to partition_create_c2c().

  Adjust dfs() 'work' array size to comply with new requirements of
  -r5088.
