An Unified Method of Finding the Inverse of a Matrix with Entries of a Linear Combination of Piecewise Constant Functions

각 항들이 구간 일정 함수의 선형 결합으로 표현된 행렬의 역을 구하는 방법

This paper presents an unified method of obtaining the inverse of a matrix whose elements are a linear combination of piecewise constant functions. We show that the inverse of such a matrix can be obtained by solving a set of linear algebraic equations.
