Simple Python Debugging with Pdb: Part 1
I’m pretty new with Python, so I was looking around for some debugging tools. At first I dismissed Pdb (Python debugger) as being too primitive, but after seeing a blog post about using Pdb, I decided...
View ArticleSolving Homogeneous Linear ODEs using Annihilators
In this Insights article we’ll look at a limited class of ordinary differential equations — homogeneous linear ODES with constant coefficients. Although there are many differential equations that are...
View ArticleSolving Nonhomogeneous Linear ODEs using Annihilators
My previous Insights article, Solving Homogeneous Linear ODEs using Annihilators, discussed several examples of homogeneous differential equations, equations of the form F(y, y’, y”, …) = 0. In this...
View ArticlePartial Fractions Decomposition
Partial fractions decomposition is an algebraic technique that can be used to decompose (break down) a product of rational expressions into a sum of simpler rational expressions. A rational expression...
View ArticleWhat Are Eigenvectors and Eigenvalues?
Two important concepts in Linear Algebra are eigenvectors and eigenvalues for a linear transformation that is represented by a square matrix. Besides being useful in mathematics for solving systems of...
View ArticleWhy Can’t My Computer Do Simple Arithmetic?
The first computer I owned was an Apple IIe computer, with a CPU that ran at slightly over 1 Megahertz (MHz), and with 64 Kilobytes (KB) of RAM, together with two 5 1/4″ floppy drives that could each...

In the first part of this article (AVX-512 Assembly Programing – Opmask Registers for Conditional Arithmetic), we looked at how opmask registers can be used to perform conditional arithmetic. That...
View ArticleAVX-512 Programming: Extracting Column Subtotals from a Table
In this Insights article I’ll present an example that shows how Intel® AVX-512 instructions can be used to read a whole row of data in a single operation, and then generate subtotals for some or all of...
