Study of numerical mathematics with a repository for numerical schemes and another one for numerical systems (linear and non-linear)
NumSchemes is a repository to study numerical schemes.
PDE/1D/ focuses on one dimensional schemes of advection related problems
with schemes detailed in Chapters 7 and 8 of Numerical Computation of Internal and External Flows: The Fundamentals of Computational Fluid Dynamics, Charles Hirsch (Elsevier, second edition, 2007)
ODE/ is an implementation of examples presented in Karen Willcox, and Qiqi Wang. 16.90 Computational Methods in Aerospace Engineering. Spring 2014. Massachusetts Institute of Technology: MIT OpenCourseWare, https://ocw.mit.edu. License: Creative Commons BY-NC-SA.
NumSystems contains for now study of simple Poisson problem matrices.
