franko/gsl-shell
GSL library shell based on LuaJIT2
franko·3y ago·April 14, 2023📋 Changes
- the gdt.append method will now add new columns to the table if required
- gdt.new and gdt.alloc will works with empty arguments to create a zero size table
- when printing a table on the screen the row number is no longer shown
- better documentation for the gdt.hist function and add a "show" option
franko·3y ago·February 22, 2023📋 Changes
- `gdt.integrate` to perform a numeric integration from the table data.
- `gdt.sampling_optimize` to remove redundant data and reduce the number of points. Here the [documentation](http://franko.github.io/gsl-shell/gdt.html#gdt.sampling_optimize).
- `gdt.from_table` to create a tables from data in Lua tables format
📦 Notes about the release files
- Where not specifically indicated in the name the packages targets a generic x86-64 CPU architecture and use the OpenBLAS library for matrix operations.
- Some specific packages are designated like the following:
- nehalem, haswell and skylake are optimized for specific Intel CPU micro-architectures.
- dynamic use OpenBLAS to choose at run-time the optimized functions for you CPU and cover a large range of Intel and AMD CPUs.
- gslcblas use the reference GSL BLAS implementation and will be much slower than OpenBLAS for large matrix or vector operations but will work for any CPU.
- The Linux packages comes in two flavours: AppImage and simple archives that can be extracted in any directory. For the archive type the executables are placed in the "bin" subdirectory.
franko·3y ago·October 1, 2022This new release finally fixes some annoying problem with the cursor positioning and the escape key not properly working. It also has a few new modules for 2D Interpolation and to store time-dependent values. This latter module is introduced especially to implement a new feature of the ODE integration module. Now it is possible, when integrating a differential equation, to compute some derived quantities and to store them in a record object to be consulted at the end of the integration period. Another addition brought by this release is the project module that let you have a main project's script that loads other project's modules using the "require" Lua function. With this release we also provide a larger number of executables to choose. The dynamic uses the OpenBLAS library to adapt dynamically to the specific CPU used at run time at the price of a larger executable. The packages marked with Nehalem, Haswell and Skylake use OpenBLAS but statically targeting the corresponding CPU. Use them if you know the CPU you are using and it matches one of those provided. Finally the GSL CBLAS executable uses the reference BLAS implementation provided with GSL library. It is safe to use and the package is smaller but matrix multiplication will be much slower. Use it if you don't care a lot about big matrix multiplications or inversions or if you have troubles with the other packages.
franko·4y ago·April 14, 2022✨ New Boxplot
- In terms of functionalities this release introduce boxplots to be used from the General Data Table.
- Now creating a boxplot from a tabular dataset is as simple as writing `gdt.boxplot(data, "income ~ gender, age")`.
- The barplot also got a related improvement to choose more nicely the bars' width based on the x axis data layout.
📝 Updated documentation hosted on github
- The documentation was updated for the new release and is now on github:
- http://franko.github.io/gsl-shell/
📦 Build and packaging modernization
- The major changes for GSL Shell are behind the curtains, in the build and packaging implementation.
- We moved to FOX 1.7 to have support for High DPI monitor of windows and other improvements.
- All the build system was moved to Meson and the source code was reorganized.
- Additional packages using GSL CBLAS instead of OpenBLAS are provided for older CPU types using only the x86-64 instruction set.
- We provide also a practical AppImage executable for Linux.
