Matrices are the foundation of Linear Algebra; which has gained more and more importance in science, physics and eningineering. The inverse of a square n x n matrix A, is another n x n matrix, denoted as A-1. The last eigenvalue: The sum of all eigenvalues is the trace, so if you have three of them, the last comes for free. Eigenvalues and Eigenvectors Calculator for a 4 X 4 Real Matrix This page contains a routine that numerically finds the eigenvalues and eigenvectors of a 4 X 4 Real Matrix. This calculator solves system of four equations with four unknowns. I asked this question in the homework forum, but desided to move it here, since I'm not in a hurry. See step-by-step methods used in computing eigenvectors, inverses, diagonalization and many other aspects of matrices Input the components of a square matrix separating the numbers with spaces. The calculator will find the characteristic polynomial of the given matrix, with steps shown. 4x4 system of equations solver. My problem: How do I find the eigenvalues of this matrix: \(\displaystyle \) \(\displaystyle \begin{bmatrix}1&-3&2&-1\\-3&9&-6&3\\2&-6&4&-2\\-1&3&-2&1\end{bmatrix} (Notice that it is symmetric, if that helps) On this site one can calculate the Characteristic Polynomial, the Eigenvalues, and the Eigenvectors for a given matrix. Find more Mathematics widgets in Wolfram|Alpha. Free online inverse eigenvalue calculator computes the inverse of a 2x2, 3x3 or higher-order square matrix. In general, you can skip the multiplication sign, so `5x` is equivalent to `5*x`. Input either decimals or fractions. In general, you can skip parentheses, but be very careful: e^3x is `e^3x`, and e^(3x) is `e^(3x)`. One of the final exam problems in Linear Algebra Math 2568 at the Ohio State University. Thus, this calculator first gets the characteristic equation using Characteristic polynomial calculator, then solves it analytically to obtain eigenvalues (either real or complex). ... but I am doubtful that multiplying 4x4 matrices four times is computationally easier than finding the characteristic polynomial. Get the free "4x4 Determinant calculator" widget for your website, blog, Wordpress, Blogger, or iGoogle. The algorithm is from the EISPACK collection of subroutines. It does so only for matrices 2x2, 3x3, and 4x4, using Solution of quadratic equation , Cubic equation and Quartic equation solution calculators. 4x4 System of equations solver.
