👉 In mathematics, a massilian is a concept used in the study of linear algebra and matrix theory. A massilian is a type of matrix that has an infinite number of eigenvalues and can be represented by a diagonal matrix with infinitely many entries. A massilian matrix is defined as follows: $$ M = \begin{bmatrix} a & b \\ c & d \end{bmatrix} $$ Where: - $a, b, c, d$ are real numbers
