If you're in 2d space, there is no 2x2 matrix that will do this transformation for all points. However, if we go one dimension higher, to a 3x3 matrix, you can! That's why OpenGL uses 4x4 matrices to describe 3d transformations, as we'll see later. The best way to explain how to make this matrix, is to give the matrix for the example above.

For an article I am writing I wanted to plot the following function: $ theta left(x frac{1}{2} right) left( sin(4 pi x) sin(4 pi y) 2 right) $. Wolfram Alpha gives the following pretty plot:. Plot from Wolfram Alpha. Use vector formats where possible, otherwise your graphics will look horrible on higher resolutions! The numbers in fr...

One of the challenges in the British game show Countdown was to find a way to create a number using other numbers and basic mathematical operators. For example, given the set {2,3,4,5} generate 14, using , -, *, /. A solution is 5 *4 - 2 * 3. Note that each number should be used exactly once. For example, $ 5 cdot 6 - 2 cdot 3$ :. For this ...

El weblog de NoP. Jueves, diciembre 06, 2012. A Little Motivation (obviam.net). Si recordáis mi entrada sobre "La Edad de Oro del Software Español", ésta acababa con una pequeña reflexión personal. Pues bien, buscando información sobre programación en Android / JAVA, me encuentro con un blog interesantísimo ( Obviam.net. Con geniales artículos sobre desarrollo de videojuegos para Android. Entre ellos, hay un artículo que intenta justificar el porqué del nacimiento del blog. I’m talking about the 80s.

For a website I am building I want to have facebook authentication, which means that users don't have to make an account. In order to use their API, facebook forces. Seriously, WTF. After all that trouble I went through, their "systems" say my account is not authentic. What does that even mean, their systems? February 22, 2012 at 11:11 AM. February 22, 2012 at 12:02 PM.

Sometimes it's very convenient to see real time updates of your gnuplot graphs, for example if you're doing Monte Carlo simulations or if you have are monitoring stocks. Below I'll show you the way I do it, by only using gnuplot commands. First, create a gnuplot configuration file called ' loop.plt. Pause 2 replot reread. And we call gnuplot w...

Telling the epic tales of science, programming and life. May quite possibly contain some ranting. Wednesday, July 4, 2012. What is the Higgs boson? Today the Higgs boson has been found at CERN, a great accomplishment in the field of theoretical particle physics. This discovery means that the model we are currently using is completed: the final ingredient has been found. This model, called the Standard Model, yields very good predictions of what is happening in nature. The mystery of the massive particles.
