Calculations of the Renner-Teller effect in various triatomic systems are carried out employing the vibronic CI method, according to which a matrix representation of the pertinent global hamiltonian is effected and the corresponding eigenvalues and eigenvectors are obtained by a single diagonalization. ...

I am using dggev (mkl versions 11.2.1 & 11.2.2) and i notice some non deterministic behaviour concerning eigenvalues near zero and infinite eigenvalues and eigenvectors. I use the parallel mkl version with gomp (not intel omp). I compile my code using gcc 4.4.7. It seems that there are...
The composition matrix and eigenvectors of the eight indicators under the principal components were calculated (Supplemental Tables S8 and S9). For the Fn equations, the EEI indicators were coded as follows: acidity (x1), fruit weight (x2), yield (x3), PFPN (x4), PFPP (x5), PFPK (x6)...
the matrix is then reformed using the modified eigenvalues and original eigenvectors (see, e.g., Daniels & Kass, 2001; Ledoit & Wolf, 2004 for discussion of variations of this type of approach, and Weston et al., 2014 and Campbell et al., 2017 for recent examples of its application). ...
I've put together a quick program to figure out how to use the MKL library to calculate the eigenvalues and eigenvectors of a real symmetric matrix A. However, I get the following error message when compiling: "Error 1 error #7002: Error in opening the compiled module file. ...
Let S be the sample variance–covariance matrix of the data; the principal components α1,α2,…,αp are simply the eigenvectors of S, and d1⩾d2⩾⋯⩾dp are simply the (ordered) eigenvalues of S. In order to determine how many principal components are needed, a number of ...
einsumis planned, and there's a PR up foreig(WIP: Add specifications for computing eigenvalues and eigenvectors#113). sqrtm(and related functions likeexpm,logm, etc.) are very hard to implement, so I'm fairly certain we don't want that one in the standard. ...
