DIAGONALISATION Meaning and
Definition
-
Diagonalisation refers to the process of finding a diagonal matrix that is similar to a given square matrix. In linear algebra, a square matrix is said to be diagonalizable if it can be written as the product of three matrices: P, D, and P^(-1), where P is an invertible matrix and D is a diagonal matrix.
The concept of diagonalisation is primarily used to simplify matrix operations and calculations, particularly in the context of eigenvalues and eigenvectors. By diagonalizing a matrix, we transform it into a simpler form that allows for easier computations and analysis.
The diagonal matrix obtained through diagonalisation has non-zero entries only on its main diagonal, while all other entries are zero. This diagonal form reveals important properties of the original matrix, such as its eigenvalues, which are precisely the entries on the diagonal.
Furthermore, diagonalization is closely related to the concept of eigendecomposition, as both processes involve finding a diagonal matrix representation of a given matrix. However, diagonalization focuses specifically on square matrices and requires the existence of linearly independent eigenvectors.
Overall, diagonalisation is a powerful tool in linear algebra that enables us to reveal crucial characteristics of a square matrix by expressing it in a simpler, diagonal form. This process offers computational advantages and aids in solving various mathematical problems involving matrices.

Etymology of DIAGONALISATION
The word "diagonalisation" is derived from the noun "diagonal" and the verb suffix "-ization".
The noun "diagonal" comes from the Latin word "diagonalis", which means "slanting line". It originated from the Greek word "diágonios", which combines "dia-" (meaning "through") and "gonía" (meaning "angle"). The concept of a diagonal line emerged from the notion of a line passing through two opposite angles of a rectangle or parallelogram.
The verb suffix "-ization" is derived from the noun "-ize" or "-ise" (spelling variation), which signifies the process of making, forming, or creating something. It is derived from the Greek suffix "-izein", which means "to render, make, or cause".
