I am working on a project where I need to compute the eigenvalues of a symmetric real matrix **A** in Python. I encountered an issue where the eigenvalues returned by **eigvalsh**, **eigvals**, and **eigh** are different. My code: import numpy as np def convert_Matrix(Var, dim): var_i = np.zeros((dim, dim)) indices = np.tril_indices(dim) var_i[indices] = Var […]
