Matrices for Engineers

A square matrix of order n can be formed from the eigenvectors of the n n square matrix A. This vector is called the modal matrix of A and is designated by M
In example 7.6, it was shown that the matrix
possesses three eigenvalues
Each of these eigenvalues is associated with an eigenvector
This linearly independent set of column vectors can be used to form the modal matrix of A by setting ? 1 = ? 2 = ? 3 = 1
