   SageMath's goal is to provide a viable free open source alternative to Magma, Maple, Mathematica, and Matlab

   I started SageMath in 2004 to provide a FOSS alternative to expensive commercial mathematics software. Sage is Python-based and has had around 600 volunteer contributors. The project has also received millions of dollars in support from grants around the world, and has a very active developer community.

   This site is about Software as a Service, and there are at least two easy ways to use Sage online as a service:

   https://cocalc.com and https://sagecell.sagemath.org/

   🏁 Competitors: Wolfram Mathematica, MATLAB, Maple, Magma

• Did studying proof based math topics e.g. analysis make you a better programmer?

  I received a Ph.D. In pure math (number theory) from Berkeley, and then worked as an academic mathematician for 20 years, so wrote a few dozen research papers and some books. My ability to write software for doing mathematics was obviously better as a result of studying mathematics, e.g., I started SageMath (https://sagemath.org) and wrote a big chunk of it. Now I mostly do full stack web development (I... - Source: Hacker News / 10 months ago

• How do I get this calculator to give me the derivative?

  You could also try sagemath (sagemath.org), available for window, mac & linux for free. Source: about 1 year ago

• Are there any good free numeric computing environments?

  SageMath gets my vote. I use it to compute simplicial objects that turn out to be infinitely categories. https://sagemath.org SageMath includes most of the python libraries already mentioned, and much more. Source: over 1 year ago

  I am a fan of this site (and of this site's tutorial in particular). I would also recommend this site. The SageMath site has some good tutorials too. Source: over 1 year ago

OpenModelica mentions (6)

• An open source, educational, low-cost modern analog computer

  I have used https://openmodelica.org/. It's another one of those "invest substantial time understanding what they are doing, and you will likely be rewarded." Simple things are simple, but I found it took longer than I would have like to bang out e.g. a PID algo with a particular motor and load. If you want to try this, buy the book, and follow it to the end. Then keep learning, as you build more and more... - Source: Hacker News / 11 months ago

• Best software for parallel robot simulation?

  If the robot simulation doesn't need to pick up stuff or take into account changing contacts with other objects you can use Modelica's Multibody library which you can run for free with OpenModelica. This will be more accurate than other simulators because modelica can analytically solve the dynamics equations. You don't need to write them either just to connect blocks for various components.

• Anyone know if python can be used to make a MATLAB simulink clone (dragging and dropping elements)? If not, do you have recommendations of other languages that can do this best to make a desktop app?

  OpenModelica consists of a combination of graphical and written components to simulate dynamic systems. I don’t know what control system feature set might be available. AMESIM is a more extensive paid tool that operates on the same Modelica modeling language. IIRC, at least Simuscape operates on Modelica under the hood. Source: about 1 year ago

• Just introduced to diffeq last year. Curious how to go about modeling something like this.

  It shouldn't be too difficult to model in Modelica. You could approximate the pendula in 1D with masses on springs or just use Modelica's multibody library. Source: about 1 year ago

• Need software recommendations please

  Modelica is a good start, at the very least in showing how to break a complex machine with many physical phenomena into components. Modeling accuracy and ease are generally opposed. Https://openmodelica.org/. Source: almost 2 years ago
