News, Tutorials, Howtos for Ubuntu Linux
Linux world got some big updates, such as XFCE 4.20, RHEL 10.0 Beta, and Linux Mint 22.1 Beta, in last days. While, many free open-source apps also released updates recently you may care about.
And, here I’m going to introduce some of them for you. They include Audacity 3.7.1, GNU Octave 9.3.0, Scrcpy 3.1, VS Code 1.96, and TeXstudio 4.8.5.
GNU Octave, the free open-source application for numerical computations, released new major 9.1.0 version! Here’s how to install it in Ubuntu 20.04, Ubuntu 22.04, Ubuntu 23.10, and Ubuntu 24.04.
The GNU website has not yet announced the new release, but it’s available in the download page.
According to the changelog, the new Octave 9.1.0 overhauled dec2base, dec2bin, and dec2hex. They now accept negative inputs and fractional inputs.
It re-architected the inputParser function to get a 60% performance improvement. And, the perms function has been made faster. The audiowrite function now supports writing to MPEG audio formats (including MP3) if the sndfile library supports it. The current directory of oruntests now changes to the directory containing the files with the tests for the duration of the test.
The release features new functions, including isenv, ismembertol, isuniform, tensorprod.
The disable_diagonal_matrix, disable_permutation_matrix, and disable_range functions have been removed! Replacements are optimize_diagonal_matrix, optimize_permutation_matrix, and optimize_range
Operators, such as .+, .+=, **, and .**= are removed. Replacements are +, +=, +=, ^, and .^=. And, following function are obsolete:
idx_vector::bool()all_ok(const Array&) in Array-util.h.octave_base_value::count
GNU Octave 6.1 was released a few days ago with numerous improvements, bug-fixes, and a list of new functions.
Changes in Octave 6.1 include:
"stable" for intersect, setdiff, setxor, union, and unique functions.web function.format command options: uppercase and lowercase (default).legend function.axis function and many other graphics backend improvements.
There’s no PPA repository contains the new release package at the moment of writing.
Before the official Snap package and the community maintained Flatpak package publish the new package, you can download & build GNU Octave from the source tarball:
