... The assertion is that PT (T ) = 0n where 0n is the n-by-n zero matrix. The main use of this is that the eigenvalues of T are the roots of PT (x) = 0. However, except for very small matrices, this is a suboptimal computational approach, and the minimal polynomial is far more useful for demonstrating ...

... β = {v1 , . . . , vn }. Because T is one-to-one, the vectors T(vk ) are distinct for 1 ≤ k ≤ n, and thus T(β) = {T(v1 ), . . . , T(vn )} is a set of n vectors in W . Now suppose that some linear combination of these vectors is equal to the zero vector of W ; i.e., suppose a1 T(v1 ) + . . . + an T(vn ...

... The sum of eigen values is equal to sum of diagonal (principle) elements of matrix, which is called trace of the matrix. Eigen vector:[ A- λI ] [λ]=0 for each λ value there is a solution X = [x1,x2,…xn] which is called eigen vector. Properties of eigen values: 1. Any square matrix A and its transpos ...

... IMPORTANT: Another example: Say we create a 1-D vector x with the following: x := [2 4 9 5 2]; Now say we want to square each number in x. It would seem natural to do this: y := x^2 But Mathcad tells us: “This Matrix must be square. It should have the same number of rows as columns” Note that y : = ...
