Linear Algebra Diagonalization Using Eigenvectors and Eigenvalues for Square Matrices
The process establishes that a square matrix $A$ is similar to a diagonal matrix $D$ if and only if it possesses $n$ linearly independent eigenvectors, which form the columns of an invertible transition matrix $P$. This theoretical framework relies on the fundamental property where the product of an operator acting on its basis of eigenvectors yields scalar multiples (eigenvalues) applied to that same vector. Consequently, any analytic computation performed in the diagonal eigenbasis can be mapped back to the standard coordinate system via the similarity transformation relation $A = PDP^{-1}$.
