#probability to generate samples of random variable
➡️ #scilab use grand() and specify the the low and parameters "def" for uniform in [0,1], "nor" for normal ... 👍
➡️ #gnuoctave use rand() for uniform in [0,1], randn() for norma N(0,1) rande() for exponential with parameter 1 , randp() for Poisson ...😐
➡️ #matlab use rand() or randn() or exprand() or ... nothing 🤦‍♂️

🎉 Successfully conducted a webinar on #Scilab and #Xcos as part of the FOSSEE project, IIT Bombay.

Sessions like these help bridge the gap between academia, industry professionals, and accessible computational tools. It is encouraging to see growing interest in Free and Open Source Software for numerical computing and engineering applications.

The Scariest Literature?

I feel Signals and Systems isn't too scary if accompanied with #MATLAB, GNU #Octave, #Scilab, or similar. And if you have #ham radio experience, you can do VERY well in this class! This did give me a run for my money in undergrad though.

Mi lernis tre malmulte #MATLAB helpante studentojn. Sed sufiĉe por helpi amikinon kun ŝiaj hejmtaskoj ĉe #Scilab.

starting from the conservation of the energy
(1/2)*m*(L(a)*a')^2+ m*g*y=Cst (1)
by derivation I get the additional term with a delta function compared to the preceding differential equation,. Then replacing this delta function by exp(-x^2/2s^2)/sqrt(2*pi*s^2), for a small s, I get a more realistic simulation. The energy is (almost) conserved (except near a=0), I should try to solve the first order differential equation (1) perhaps I will get a better result ...
#physics #mathematics #scilab

I try to simulate an asymmetric pendulum, which length L(alpha) is l for alpha>0 and l/2 for alpha<0. I though the situation can be described by the differential equation :
L(alpha)*alpha'' +g*sin(alpha)=0
but when I plot the total energy over the time
E= (1/2)*m*(L(alpha)*alpha')^2+m*g*y
it is not constant !?! So I probably loose some term in the equation ...

Now #scilab accept anonymous functions definition with a syntax close to #matlab #gnuoctave , this make translation between this langages easier. For example :

f=@(t) exp(-t.^2); %% octave syntax
f=#(t) -> (exp(-t.^2)); // scilab syntax

@jbowen

I have only used Octave in Machine Learning courses

With my low usage of it, I have seen it as super close equivalent to Scilab

Do you know if (and why) one is preferred over the other? #octave #scilab

#vacancesdeprof avant de me lancer dans la correction de copies j'ai décidé de m'inscrire à un #mooc sur l'analyse de données car je vais devoir monter un cours sur le sujet (cours dont personne ne veut apriori donc ça tombe sur moi pour avoir mon service) :

https://www.fun-mooc.fr/fr/cours/analyse-des-donnes-multidimensionnelles/

Toujours intéressant d'approfondir un sujet qu'on a juste effleuré et puis c'est l'occasion de refaire de l'analyse en composantes principale et de jolies visualisations (avec #scilab bien sûr!)

Моделирование управления AC двигателя — Field oriented control of PMSM с помощью opensource решений

В этой статье я хочу поделиться результатом своих исследований в области моделирования систем управления двигателями переменного тока. В качестве объекта управления был выбран синхронный двигатель с постоянными магнитами PMSM (Permanent Magnet Synchronous Machine) как наиболее распространенная машина в современных транспортных средствах. Основное внимание будет уделено построению математической модели системы, объекта управления, и алгоритмов для симуляции. Для реализации модели я выбрал open source решения: Python control, Scilab. Мне было интересно, возможно ли использование свободных средств моделирования для построения более-менее сложных и реальных систем. Далее я поделюсь своими впечатлениями. В первой части статьи приводится теоретический материал, где описываются основные уравнения двигателя и элементы теории управления. Для теоретической части необходимы базовые понимания электротехники, ниже приложу ссылки, где можно обновить знания. Я постарался проработать разные источники литературы, чтобы взять необходимый минимум, с которым самому пришлось столкнуться для понимания сути процессов управления двигателем. Читатель вправе пропустить матчасть и перейти сразу к описанию реализации, и при необходимости вернуться к некоторым теоретическим аспектам в этом материале, или других источниках. Реализация алгоритмов управления построена по классическому принципу с помощью диаграммы потоков.

Hab mrr gestern #scilab aus dem Tarball installiert v. 2024.1
Scheint jetzt auch mit Wayland zu funktionieren
Installation ging nicht ganz glatt

sudo ln -s /usr/lib/libtinfo.so.6 /usr/lib/libtinfo.so.5

Ich will den PID-Regler. Den gabs doch als Beispiel ?

"CAS" generally stands for a "Computer Algebra System". It encompasses statistical packages and programming languages like #Maxima, #Octave, #R, #Scilab, #Sage, #KAlgebra, #Qalculate!, #Python, #Julia, #Lua. You can use them all concurrently in multiple #LabPlot's notebooks.

Please, see the attached screenshot. In this case, Python 3.12.3 is available in LabPlot on a Ubuntu machine.

Testei o #scilab 2024 e gostei. Portei um exercício em #python facilmente. Havia usado muitos anos atrás como alternativa ao #matlab quando estudava.
Os pros são: Linguagem muito simples, plotagem performa melhor que matplotlib(usa opengl).

Cons: É uma ferramenta de pesquisa e estudo. Não é para usar em engenharia de dados.

Mas é sensacional. Estou até cogitando em voltar a usar para prototipar algoritmos.

Now that #SciLab is back, our mollusc #shell #growth simulations are back too! Trying out a new tool from the group that build #DataGraph called #ImageTank with one of our simulated growth increments series of Nautilus shell shapes.

#Scilab 2024.0.0 works like a rocket on #AppleSilicon, even with a middle of the road configuration. We've been doing some tests with code from our last article and they now run in 1/3 the time of our previous PC-based machine. Crossing our fingers that we will get funded to upgrade a second system!

Exploration de nouvelles idées pour travailler sur la résolution d'équations différentielles, y a pas que l'attracteur de Lorenz, celui de Rössel est pas mal aussi, on a l'impression de dessiner un trou noir!
#mathematiques #scilab

@guites a programação sempre encontra a matemática. A diferença é que a gente usa um problema que já foi resolvido por alguém. 😉 O legal é que existem ferramentas para você prototipar algoritmos como #gnuoctave, alternativa para o matlab, o #scilab e até linguagens como #python ou #julialang. Mas imho, octave é muito simples de usar

Liebe Studies und Nachwuchswissenschaftler*innen, wenn eure Excel-Tabelle so aussieht, dann ist Excel einfach das falsche Werkzeug.

Wer möchte hier mögliche Fehler suchen?

Probiert unbedingt mal #MATLAB, #Octave, #Scilab, #Python oder eine andere Skriptsprache.

Der initiale Einarbeitungsaufwand lohnt sich.

I’m a little late with this good news, but #SciLab is back with a version updated to run on the #applesilicon chips … and it is fast! 👩🏻‍💻

@runjaj me encantó #Scilab en los 90, cuando estaba buscando una alternativa abierta a #Matlab y no había #Octave para Mac OS (nótese las mayúsculas y el espacio). Por compatibilidad de scripts, acabé utilizando #RLab2, pero siempre me quedó el afecto por #Scilab…

No estaba muerto, estaba de parranda.

#Scilab ha publicado una nueva versión de su programa/lenguaje/simulador gráfico:

La verdad es que lo hizo hace un mes pero yo me enteré ayer.
