Hi, can ELPA only get half of the symmetric matrix and compute the eigenvalue and eigenvector? Just like ScaLAPACK pdsyevd?
There is a symmetric matrix that will be transformed before computing it…

I read your code carefully and I have a question about the PCA part in the "main.m".
As I know, to play the PCA on "A", we need to get the eigenvectors of "A^T*A". And these sorted eigenvectors form …

I create an int random symmetrical matrix and calculate the transposed matrix, which should be identical.
The matrix == operator compiles, but performs false on comparison,
An extended method, which…

I think I figured out the general technique for simultaneously finding eigenvalues and eigenvectors for any matrix...numerically.
use power iteration to find largest...this gives both the value and…

Sometimes I want to do matrix manipulations that involve using a matrix whose columns are various eigenvectors from the EVP solver. A good example can be found [here](https://github.com/DedalusProject…
