Here is a minimal example of the SVD code
```
public class Svd {
static Logger logger = LoggerFactory.getLogger(Svd.class);
static public void svd(double A[][], double U[][], double S[],…

Dear yixuan,
Thank you very much for developing the package as a c++ alternative of ARPACK. It helps me a lot.
Currently, I am using SPECTRA to solve the frequency problem in Finite Element Method…

Hi, I built lapack with xlf on a ppc64le (POWER8) machine. I used the options in `INSTALL\make.inc.XLF`, although for my `BLASLIB`, I switched to `../../librefblas.a`.
During `make`, I encountered…

We believe that the inclusion of an annealing simulator in the first release of Qibo is a good idea.
One possibility is to implement the QUBO graph and then proceed with the following algorithms:

The is_positive_definite does not always give a result. In the example below with a 4x4 matrix, which numpy can demonstrate is posdef, sympy returns neither False nor True but None. None is interprete…

Checked the eigenvalues in ex17 and they seem to be a bit high for my taste, so I'm not sure whether the equations are correct or not.
Found an analytical test case from https://cfwebprod.sandia.go…

I have discovered that my concepts and code for the OPTI and OPTTI symmetries of chord space were wrong, and therefore wrongly implemented. This is to fix that in both JavaScript and C++ and thus make…
