GSL shell is an interactive command line interface that gives easy access to a collection of numeric algorithms and functions based on the GNU Scientific Library (GSL). GSL Shell is able to work with matrices or vectors to perform linear algebra operations.
You can download the latest release of GSL Shell in the download section. You will find the source code and the binary packages for Windows and Linux.
GSL Shell 2.3.0 released.
The new chapter about GDT tables is now complete with a lot of examples.
A lot of work was done to improve the linear model function to treat correctly the corner cases and degenerate models. A functions to initialize GDT tables have been improved for greater simplicity. The function to create histograms was also improved over the first implementation. A new, useful, interpolation function for GDT table is also introduced.
A new blog about GSL Shell but not only.
I'm beginning to post some interesting things about GSL Shell or Math in general in a blog at the address http://gsl-shell.blogspot.fr. If you are interested in GSL Shell, maths or computer science you may find some interesting posts!
GSL Shell 2.3.0-beta1 released.
This new release introduce General Data Table (gdt) used to store observations data in tabular form. They are very similar to the well known GNU R's data frames.
General data tables open the ways to a whole family of functions that operates on table. By using a simple declarative language you can easily create plots based on the table's data or perform statistical analysis.
A function to make linear model fit of data is introduced like the "lm" function in GNU R.
In addition now it is possible to easily create plots with multi level labels on the axis. This is very useful to plot data based on multiple nested factors.
The new functions are documented in the General Data Table's chapterof the user manual.
GSL shell is free software, everyone can freely use it, adapt or study the source code. You can contribute to its development by making a donation:
GSL Shell comes with a quite complete user manual. If you want to learn more about GSL Shell you can read with the introduction to GSL Shell. You may also give a look to the examples section to get a feeling of GSL Shell.
