The Fortran interface to C++ fuction MaponiA3() works but the mechanism of passing the 2D arrays from Fortran to C++ must be improved. Now the passed 'linear' 2D arrays are copied and reshaped into usable 2D arrays. This needs to be replaced with some suitable casting mechanism.

Solved linking problem by including C++ standard library '-lstdc++'. Also added a minimal working example of Fortran-C++ interfacing in dir 'mwe'.

Prepared the example matrix of Example 8 of the paper and its
...
decomposition in the Fortran code and made a basic call to the
subroutine MYSUBROUTINE, which is bound to the C++ void function
'Sherman-Morrison();. For now compilation fails with lots of undefined
references.'

Prepared the main Fortran infrastructure for the C++ calls. Updated the makefile.

Fix/upd inverse

Update of A0_inv fixed. matMul(...) breaks link between A0_inv and Slater_inv. Fixed by creating a new pointer that points to where Slater_inv points to before it gets reassigned by matMul(...) and then copy the updated elements back to the passed array pointed to by the new pointer.

Problem fixed: template function definitions (implementations) need to be fully known in the header file (.hpp) and not in the implementation file (.cpp).

Split the program in a header file and an implementation file and included them in main. Does not compile. Get the following error: ld: /tmp/icpcnmVxvw.o: in function void showMatrix<int>(int**, unsigned int, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)'

Extracted the SM algorithm and wrote it as a void function that updates the passed old inverse. Does not work yet. For some reason the changes in the inverse do not persist when the function is finished. Also the inverse is not correct.

Added random matrix initialisation of arbitrary size. Added function to calculate determinant to test matrix invertability of A and A0.

Converted overloaded functions into templates. Removed second size argument from the showMatrix function since we are only interested in square matrices.

Maponi algorithm 4 works for the modified Example 18 in the paper but not for general non-singlual NxN matrices yet.
