Although the topic has been addressed succinctly in a CentOS forum post, there are certain things like plymouth configuration post Nvidia driver install, etc. which I felt needed to be jotted down for reference.

Ever faced the problem of running executables in a MATLAB installation on Linux. I frequently use an executable file (.exe) provided by an eminent research lab, but the linux enthusiast that I am, shifting to Windows just for running this file is out of the question!

MATLAB: Run m-file From Linux Terminal / DOS

aspratyush — Sun, 12 Feb 2012 08:42:59 +0000

Yes, MATLAB m-files can very much be executed without initiating the MATLAB GUI. This can be quite handy when when running multiple codes simultaneously without creating a huge clutter for the user, or when running multiple instances of MATLAB and there is a need to prevent unnecessary eating up of the RAM through its GUI.

It so happens that at times the SSH connection was getting lost (probably due to network issues) with a message “Write failed: broken pipe”, and this resulted in a crash in cluster based codes. Thanks to this Archlinux forum post, i understood the workaround. Broken pipe results upon communication loss between the client and the [...]

Experience Gnome3.2 in Fedora 16 via Virtualbox

Matlab provides a nice and simple way to generate continuous set of variable names, say in the form of var1, var2,… etc. This can be accomplished using genvarname and eval commands. Here i’ll show an example where we need to store columns of a matrix A in 3 vectors var1, var2 and var3. Following is [...]
