WebApr 21, 2024 · SymPy is a Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible. SymPy is written entirely in Python. WebIn NumPy, there is a method for finding the eigenvalues and eigenvectors and it is linalg.eig (). The syntax of this function is below. linalg.eig (a) Here “a” is the input square matrix. This function returns two values w and v. The w is the eigenvalues and v is the eigenvector. In the next section, you will learn how to find them with steps.
