  1. 1. A Numerical Investigation of Different Methods for Computing the Matrix Exponential

    Kandidat-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Författare :Yvonne Cherotich; [2021]
    Nyckelord :matrix exponential; algorithms; efficiency; accuracy; Mathematics and Statistics;

    Sammanfattning : Matrix functions and their applications play an important role in different fields of science and engineering. The matrix exponential is one of the most important and extensively used function of matrices. The computation of the exponential of a matrix is an interesting topic that has been extensively studied over the years. LÄS MER

  2. 2. Comparing Multistep Methods Within Parametric Classes to Determine Viability in Solver Applications

    Master-uppsats, Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Författare :Michael Andrew Kraut; [2021]
    Nyckelord :Ordinary Differential Equations; Initial Value Problems; Linear Multistep Methods; Numerical Analysis; Numerical Solvers; Parametrized; Algorithms; Control Theory; Mathematics and Statistics;

    Sammanfattning : In the 2017 paper by Arévalo and Söderlind, a framework was established for creating linear multistep methods of various classes based on a polynomial formulation which includes variable step size adaptivity. These classes are: k step explicit and implicit methods of order k and k+1 respectively for nonstiff problems (such as Adams methods), and k step implicit methods of order k for stiff problems (such as BDF methods).

    Sammanfattning : Unmanned aerial vehicles are a popular choice for various transport and monitoringapplications. In many outdoor applications frequent variations of thevehicle conguration and time-varying disturbances originating from the environmentare expected. LÄS MER

  5. 5. Finite Difference Methods for the Black-Scholes Equation

    Kandidat-uppsats, Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Författare :Asima Parveen Saleemi; [2020]
    Nyckelord :Option pricing; Generalised Black-Scholes model; Finite difference methods; Stability; Convergence; Numerical solution;

    Sammanfattning : Financial engineering problems are of great importance in the academic community and BlackScholes equation is a revolutionary concept in the modern financial theory. Financial instruments such as stocks and derivatives can be evaluated using this model. Option evaluation, is extremely important to trade in the stocks. LÄS MER
