What does eigenvector mean?

An eigenvector is a vector whose direction remains unchanged when a linear transformation is applied to it. Consider the image below in which three vectors are shown. This unique, deterministic relation is exactly the reason that those vectors are called ‘eigenvectors’ (Eigen means ‘specific’ in German).

Are eigenvectors orthogonal?

In general, for any matrix, the eigenvectors are NOT always orthogonal. But for a special type of matrix, symmetric matrix, the eigenvalues are always real and the corresponding eigenvectors are always orthogonal. The PCA is applied on this symmetric matrix, so the eigenvectors are guaranteed to be orthogonal.

What is the trace of a matrix?

In linear algebra, the trace (often abbreviated to tr) of a square matrix A is defined to be the sum of elements on the main diagonal (from the upper left to the lower right) of A. The trace of a matrix is the sum of its (complex) eigenvalues, and it is invariant with respect to a change of basis.

How many eigenvalues does a 3×3 matrix have?

So a square matrix A of order n will not have more than n eigenvalues. So the eigenvalues of D are a, b, c, and d, i.e. the entries on the diagonal. This result is valid for any diagonal matrix of any size. So depending on the values you have on the diagonal, you may have one eigenvalue, two eigenvalues, or more.
