  15. Hi!
  16. I am looking for an efficient algorithms for finding
  17.  the inverse of sparse matrix.
  18. The matrix has the following structure :
  19.  
  20.  xxxxxx00000...00000xxxxxx0000...000 
  21.  0xxxxxx00000...00000xxxxxx0000...00
  22.  00xxxxxx00000...00000xxxxxx0000...0
  23.  .                                 .
  24.  .                                 .
  25.  .                                 .
  26.  xxxxxx00000...00000xxxxxx0000...000 
  27.  0xxxxxx00000...00000xxxxxx0000...00
  28.  00xxxxxx00000...00000xxxxxx0000...0
  29.  
  30. I looked in Numerical Recipes with no result.
  31. I will appreciate any references to code/algorithms.
  32.  
  33. Thanks 
  34.  Shaul.
