The term "matrix pencil" refers to a mathematical concept used in the field of linear algebra, particularly in the context of systems of linear equations, control theory, and numerical analysis. A matrix pencil is typically denoted in the form: \\\[ \\mathcal\{A\}(\\lambda) = A - \\lambda B \\\] where: - \\(A\\) and \\(B\\) are given matrices, - \\(\\lambda\\) is a complex variable.
