The motivation for these open-source programs seems to be the desire for low-cost alternatives to established math packages such as MathCad, Maple, and Maple Flow.

In many packages, equations are live-linked in a manner resembling that of a spreadsheet so their values update when something changes.Īnd happily, many such engineering software packages are now available for free or nearly so. Generally, software users can add equations, text, and images in a freeform manner. That’s because this kind of software frequently supports all measurement units, allowing English and metric units to be mixed in equations without fear. If engineers working on the Orbiter had access to today’s software for engineering math, the spacecraft might still be happily orbiting the Red Planet. NASA had used metric units while spacecraft builder Lockheed Martin had used English units. What caught the public’s attention wasn’t so much the failed mission as the cause of the failure: An investigation found a measurement mismatch between two software systems. The Mars Climate Orbiter made headlines back in 1999 when it approached Mars on a trajectory bringing it too close to the planet and wound up either destroyed in the Mars atmosphere or orbiting the Sun. The only true way to know is to test them all on your rig using your processing code.Numerous open-source software packages now provide engineering math capabilities and go easy on the pocketbook. Not sure about performance of freemat but I don't think it is as developed as Octave. Spyder is an ide that uses python and scipy, scilab is a mash of octave and maxima and a few others.
If you want performance and you wan't to use free software best to look at scipy.

However, you can get all modern versions of Matlab running on Linux (if you have a licence) and they are included on the install disk by default now, and performance of Linux version of Matlab is as good and often better on Linux when compared to Windows.

Octave will not run (natively) some of the inbuilt GUIs like inputdlg etc, if you install Qtoctave (an IDE for Octave, sudo apt-get install qtoctave) you can use xmlwidget and a wrapper to get that functionality (I can post code if you are interested).Īs far as performance is concerned, Octave is not as fast (google for benchmarks). In fact, apart from some of the expensive Matlab toolboxes, Octave should run 98% (a number I just made up) of your code. Of all the ones you have listed Octave is the most syntax compatible. 10.04_lts 12.04_lts (the _lts is required in 'y'), etc.) 'z' refers to the architecture of your OS. Where 'x' refers to the bits of your OS 'y' refers to the version of Ubuntu the sage is designed for (e.g. Sudo ln -s /home/username/sage-linux-xbit-ubuntu_y-z-Linux/sage /usr/local/bin/sage
Sudo mv sage-linux-xbit-ubuntu_ /home/username After this copy and paste the following commands into terminal ( Ctrl+ Alt+ T): cd ~/Downloads SageMath may be downloaded by going to the website and selecting a suitable mirror, based on where you are and then installing the relevant. I would also recommend SageMath as it includes GNU Octave, (if its already installed on your system) Scilab, (if you already have it installed) NumPy, Scipy, Matplotlib, maxima, Fortran among many others. It requires you to learn some of the Python programming language, that is, if you plan to do well at it. The problem with it is that it has only limited compatibility with MATLAB, syntax wise. I have used Spyder, but only briefly I'm afraid.

The plus side, however, is that its syntax is highly compatible with MATLAB's. Third as a result of my second piece of evidence its functions are somewhat lagging. Second, it isn't frequently updated, the latest version in the software centre, was last updated in 2008.
My evidence for this is three part: firstly, in the software centre it receive the lowest star rating of the four software in question. It has some differences in terms of syntax but nothing you can't get your head around if you search the documentation that comes with it.įreeMat is the worst, in my opinion at least, of software that's syntax is heavily based on MATLAB. Scilab is an adequate replacement for MATLAB too. QtOctave is a frontend (GUI) for the GNU Octave programming language. I don't know if you're aware of QtOctave. The only differences, I'm aware of at least, aside from the odd toolbox, which you can attempt to replace by the packages here is that GNU Octave can define functions from the command line. Its syntax has an extreme compatibility with that of MATLAB. FreeMat and Spyder I do not have too much experience with, but I have some. Well you're in for a treat I have used all the programming languages/software you mentioned.
