WitrynaIn mathematics, a Hermitian matrix (or self-adjoint matrix) is a complex square matrix that is equal to its own conjugate transpose —that is, the element in the i -th row and j -th column is equal to the complex conjugate of the element in the j -th row and i -th column, for all indices i and j : Hermitian matrices can be understood as the ...

"WitrynaTo answer the original question: it's rarely the case that you want all eigenvalues of a large sparse matrix. Usually, you want extrems or some cluster of interior values. In that case, for a Hermitian matrix eigsh is faster. For non-Hermitian, you will have to go with eigs. And they are much faster than numpy eig or eigh. " - Hermitian python
