6cd9fb1072 - Moved transposing of Slater_inv to HDF5 conversion tool and removed it from the test program. 
- Let Maponi A3 continue, even after the algorithm breaks down.

6012b9decf 4x4 with 2 updates example is working again after adding update cycle 8169 dataset but with replacement updates instead of additive updates. 2021-03-12 15:49:02 +01:00
François Coppens
ef97b40196 Changed code to treat the dataset as replacement updates, instead of additive updates. Before the updates are used to compute the inverse they are transformed accordingly. 
However, this breaks the 4x4 example in update cycle 8169.

4bd61dd76c Add a standard Sherman-Morisson implementation 
- It can serve as a baseline reference

- It can serve as a starting point for including the pivot
  and splitting techniques from Maponi and Slaggel without the full
  complexity of the MaponiA3 algorithm

3df8d33bfa Problems with MaponiA3 when calling from C++ with HDF5 datasets is fixed. Bug was caused by uninitialised values of NEWed variables at several places. There are still a few remaining memory leaks. Explore with: 
valgrind --track-origins=yes --leak-check=full --show-leak-kinds=all

225c841a88 * Fixed the 3x3 MaponiA3 C++ example. Update_index vector cannot have values that are smaller than 1 because the first colums in Fortran is stored at 1 and not 0. 
* Started debugging reading from HDF5 formatted datasets. Slater_inv needs to be transposed before sent to Maponi. Algo fails at the last step. Correct Slater and Inverse fail to produce the identity matrix. Suspect that the matMul function is not working correctly eventhough it looks like it does.

b4787e6803 Test infrastructure for hdf5 datasets and python hdf5 datasert conversion tool. 
Made small corrections to compensate for changes made after branching-off from test_dataset.

Everything compilers
Everything works except for the HDF5 dataset test program that gives an I/O error.

b2b4756b53 Problem solved. Problems was caused by reading the inverse matrix S_inv the same way as the matrix S, but apparently what has been stored is transpose(S_inv) and not S_inv. Therefore it needs to be read transposed compared to S in order to for S*S_inv to give the Identity matrix. 
TODO: Calls from C/C++ are still broken because inside the MaponiA3 algo there is compensation for the fact that Fortran sends it's arrays in column-major order. This must be resolved by  transposeing S_inv before it is passed to MaponiA3 and remove the compensations made there.

8d63dd1701 The algorithm now works for the following 4x4 example with 2 updates: 
S = [1,0,1,-1; 0,1,1,0; -1,0,-1,0; 1,1,1,1]
S_inv = [1,-1,1,1; 1,0,2,1; -1,1,-2,-1; -1,0,-1,0]
u1 = [0,-2,0,0]
u2 = [0,-1,0,0]
upd_idx = [2,4]

To go from Maponi's examples where the number of updates is always equal
to the the dimension of the matrix, and the decomposition is always
diagonal, to cases with a non-diagonal decomposition and a number of
updates unequal to its size, the following changed needed to be made:

* in the calculation of the {y0k} an extra inner for-loop needs to be
  added to make it a full matrix-vector multiplication due to the fact
  that A0 is not a diagonal matrix

* in some places the use of the update-order vector p needs
  the be replaced with that of upd_idx to make sure the correct
  component of the ylk is selected and the proper rank-1 matrices are
  constructed

* when a matrix is passed from Fortran to C++ with 2D adressing, it is
  passed in colum-major order. The passed matrix needs to be transposed
  before passing to C++. Doing this inside the algorithm will break
  compatibility with called from C/C++.
