    Accurate Approximation of the Matrix Hyperbolic Cosine Using Bernoulli Polynomials 
    Alonso Abalos, José Miguel; Ibáñez González, Jacinto Javier; Defez Candel, Emilio; Alvarruiz Bermejo, Fernando (MDPI AG, 2023-02)
    [EN] This paper presents three different alternatives to evaluate the matrix hyperbolic cosine using Bernoulli matrix polynomials, comparing them from the point of view of accuracy and computational complexity. The first ...

    New Hermite series expansion for computing the matrix hyperbolic cosine 
    Defez Candel, Emilio; Ibáñez González, Jacinto Javier; Peinado Pinilla, Jesús; Alonso-Jordá, Pedro; Alonso Abalos, José Miguel (Elsevier, 2022-07)
    [EN] There are, currently, very few implementations to compute the hyperbolic cosine of a matrix. This work tries to fill this gap. To this end, we first introduce both a new rational-polynomial Hermite matrix expansion ...
