Theühikmaatriksit refers to the identity matrix in Finnish. An identity matrix is a square matrix where all the elements on the main diagonal are ones, and all other elements are zeros. It is denoted by the symbol I, or sometimes $I_n$ where n represents the dimension of the square matrix (e.g., $I_3$ for a 3x3 identity matrix).
The identity matrix possesses unique properties that make it fundamental in linear algebra. When an identity
Identity matrices are crucial for various operations, including matrix inversion. The inverse of a square matrix
