How to solve an eigenvector problem
WebFeb 24, 2024 · To find an eigenvalue, λ, and its eigenvector, v, of a square matrix, A, you need to: Write the determinant of the matrix, which is A - λI with I as the identity matrix. Solve the equation det (A - λI) = 0 for λ (these are the eigenvalues). Write the system of equations Av = λv with coordinates of v as the variable. WebThis is implemented using the _geev LAPACK routines which compute the eigenvalues and eigenvectors of general square arrays. The number w is an eigenvalue of a if there exists a vector v such that a @ v = w * v. Thus, the arrays a, w, and v satisfy the equations a @ v [:,i] = w [i] * v [:,i] for i ∈ { 0,..., M − 1 }.
