WebI have a Texas Instruments TI-85 (quite an old calculator and superseded now). It's the same as the calculator Sal uses a lot on the screen. On that there is a MATRX area where you can enter a matrix. Then you can choose the MATH submenu and choose the eigVl and eigVc menu items for eigenvalue and eigenvector respectively. WebWhat is the definition of eigenvector? How would you find the eigenvalues and eigenvectors of an arbitrary square matrix? An eigenvector is a nonzero vector which is mapped by a linear map (think matrix) to a multiple of itself. That multiplier is called the eigenvalue belonging to that eigenvector.
