I previously did an analysis of JASSM's reliability using Octave. It's a very simple exercise using the built-in Octave function em...

The Joint Air-to-Surface Stand-off Missile has been in the news lately. It's the same old story that's been going on ever since ...

I found a really simple how-to for creating custom Google search engines and used it to make my own little Open Source Math Tools search e...

An interesting discussion about an old topic just popped up on the Octave lists. It's not interesting because someone noticed that fa...

There was an interesting thread on the Octave mailing lists recently about vectorizing matrix slice extraction. That is avoiding the drea...

Tikhonov regularization is a pretty cool concept when applied to image processing. It lets you 'de-blur' an image, which is an ill-...

Gilbert Strang discusses the use of a neat built-in function in Octave, kron() , that's pretty useful for doing multidimensional finite ...

Gilbert Strang has an interesting example in one of his linear algebra lectures on eigenvalues that is relevant to the articles I've wr...

Speed seems like a continuing theme on the Octave mailing lists, a recent thread on the list of " comparing the executive speed with Ma...

In a previous post we found that speeding up Octave amounted mostly to avoiding for loops. The simplest way to do that is to operate direc...

The first part of my aeroponics project ( overview ) is turning those blue and red LED Christmas lights into a grow lamp. The basic desig...

Can you use a commodity webcam as an el-cheapo analog to digital converter (ADC)? The folks at slashdot want to know so they can reduce the...

Finite differences are cool, but you are limited by subtractive cancellation ( section 3.4: subtractive cancellation exercises ). What if y...

The shuffle, also known as the Fisher's Exact Test , is a permutation test that can be used to estimate the sampling distribution of a ...

I like Bayes theorem , it's really useful. The most intuitive and accessible explanation I've found of using Bayes theorem to solve...

The answer, like most things worth asking the question about, is "Well, it depends..." I'm not going to talk about "compu...
