- Relationship between the Inverses of a Matrix and a Submatrix E. Juárez-Ruiz R. Cortés-Maldonado F. Pérez-Rodríguez Computación submatrix Matrix inverse discrete Fourier transform A simple and straightforward formula for computing the inverse of a submatrix in terms of the inverse of the original matrix is derived. General formulas for the inverse of submatrices of order − as well as block submatrices are derived. The number of additions (or subtractions) and multiplications (or divisions) on the formula is calculated. A variety of numerical results are shown. 2016 artículo científico 1405-5546 https://www.redalyc.org/articulo.oa?id=61547018008 en http://www.redalyc.org/revista.oa?id=615 Computación y Sistemas application/pdf Instituto Politécnico Nacional Computación y Sistemas (México) Num.2 Vol.20
