Welcome to the latest Month of Math Software here at WalkingRandomly. If you have any mathematical software news or blogposts that you’d like to share with a larger audience, feel free to . Thanks to everyone who contributed news items this month, I couldn’t do it without you.
The NAG Library for Java
The Numerical Algorithms Group (NAG) have been producing numerical libraries for over 40 years and .
MATLAB-a-likes
Version 3.6.4 of , the free, open-source MATLAB clone has been released. This version contains some minor bug fixes. To see everything that’s new since version 3.6, take a look at the . If you like MATLAB syntax but don’t like the price, Octave may well be for you.
The frequently updated is now at version 20.98 with a full list of changes . Scanning through the recent changes log, I came across the very nice iteratefunction which works as follows

Numpy is the fundamental Python package required for numerical computing with Python. Numpy is now at version 1.7 and you can see what’s new by taking a look at the
Spreadsheet news
A new version of Microsoft Excel, the 800 pound gorilla of the spreadsheet world, was actually released back in January as part of Office 2013 but I managed to miss it somehow.

Another improvement I want to point out is the fact that the .
R and stuff
A new version of R, the open source standard for statistical computing, has been released. Version 2.15.3 is probably going to be the last release before version 3 comes out. The full list of changes can be found at

This and that
The commercial computer algebra system, Magma, has seen another incremental update in.
The NCAR Command Language was
IDL was updated to . Since I’m currenty obsessed with random number generators, I’ll point out that in this release IDL finally moves away from an old Numerical Recipies generator and now uses the Mersenne Twister like almost everybody else.
