4e7c4de0e8 tests/test_internal_h5 and test_external_h5 updated to use replacement updates instead of additive updates. 2021-03-12 16:18:03 +01:00

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

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

f5a2e635cf Added environment variables source script. Added test script that loops over update cycles. Added test program that loops internally over test cycles. 2021-02-28 09:28:42 +01:00

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.
