If you are a math teacher in 2025, you have likely had The Conversation in the faculty lounge. It usually goes something like this:"I assigned a worksheet on qu ...
Tessellations aren’t just eye-catching patterns—they can be used to crack complex mathematical problems. By repeatedly ...
Abstract: The Gaussian elimination (GE) is an important direct method that transforms the initial linear system into an equivalent upper triangular system, which is straightforward to solve. To ensure ...
Abstract: I develop inverse scattering methods for velocity reconstruction in the subsurface, based on multiple scattering theory, Gaussian beams and nonlinear Born approximation. This method is based ...
Final project @ Numerical Linear Algebra (数值代数) at Peking University. Consider the Stokes equations: $$-\Delta \vec{u} + \nabla p = \vec{F}, (x, y) \in (0,1 ...
When you are doing division, it's helpful to use a written method. This can be especially useful if the numbers get too big to calculate in your head. If the number you are dividing by (this is called ...
See [1, Section 4] to learn how to use the software, or check our Jupyter notebook available at /example/demo EigenvalueSolver.ipynb. [1] Bender, M.R. and Telen, S., 2021. Yet another eigenvalue ...
