1. Communication systems: Eigenvalues were used by Claude Shannon to determine the theoretical limit to how much information can be transmitted through a communication medium like your telephone line or through the air. This is done by calculating the eigenvectors and eigenvalues of the communication channel (expressed a matrix), and then ...

j=1 λ j (18.21) just as the R2 of a linear regression is the fraction of the original variance of the dependent variable kept by the ﬁtted values. 2Exception: if n< p, there are only distinct eigenvectors and eigenvalues.

P is symmetric, so its eigenvectors .1;1/ and .1; 1/ are perpendicular. The only eigenvalues of a projection matrix are 0 and 1. The eigenvectors for D 0 (which means Px D 0x/ ﬁll up the nullspace. The eigenvectors for D 1 (which means Px D x/ ﬁll up the column space. The nullspace is projected to zero. The column space projects onto itself.

Eigenvalues & Eigenvectors Example Suppose . Then . So, geometrically, multiplying a vector in by the matrix A results in a vector which is a reflection of the given vector about the y-axis. We observe that and. Thus, vectors on the coordinate axes get mapped to vectors on the same coordinate axis. That is,
