Example of the Matlab Precision Issue

Example of the Matlab Precision Issue

I noticed that there are many people comparing Matlab with Maple, Mathematica etc. to find out what’s the best Maths package for them. But many of them didn’t realize the limitations of Matlab. I put up an article about the Birthday Problem in probability, If you try to solve it analytically like:
11 – factorial(365)/factorial(336)/365^30
You will [...]

Birthday Probability Problem

In a group of at least 23 randomly chosen people, there is more than 50% probability that some pair of them will have the same birthday. Such a result is counter-intuitive to many. In probability theory, thi is known as the birthday problem, or birthday paradox. Here is how we calculate [...]

How to write a book with R and LaTeX

How to write a book with R and LaTeX

Think faster than “How to write a book in 28 days”. With the freely available R language you can create a book in less than 28 seconds. Unfortunately, you still have to write the text and do the programming. What you can do is integrate the R code and text into the same files, then [...]

Howto Create Great Presentations using Beamer, Sweave and LaTeX

Howto Create Great Presentations using Beamer, Sweave and LaTeX

To achieve this goal, we need use the concept of literate programming, yet another one of Donald Knuth’s contributions to the world. LP “represents a move away from writing programs in the manner and order imposed by the computer, and instead enables programmers to develop programs in the order demanded by the logic and flow [...]

sigTOOL: A MATLAB Toolbox for Biological Signals Analysis

This paper describes a software package for processing biological signals that has been designed to overcome this by assisting and promoting the sharing of laboratory-developed software. The package, called sigTOOL, has two components: [1] a software development environment designed to facilitate further programming by the end-user and [2] an application implemented through that environment to [...]

TopoToolbox: a set of Matlab functions for topographic analysis

The integration of spatial and non-spatial analysis software aims at providing a combination of the most efficient and powerful tools available in both environments (Brenning, 2008). There are various examples where this has been accomplished using access links between different software packages. JGrass, for example, provides integration of the statistic R package into the scripting [...]
