![]() The main downside of MATLAB is that it has some trouble running in some Linux distributions. You have also the option of getting the cheap student license. So, if your university has licenses for MATLAB and the toolkits you need, then count your blessings and use it. ![]() It also computes faster problems like Gaussian Elimination or Conjugate Gradient than its open source competitors. There is also a big community that develops free libraries for MATLAB. ![]() ![]() It has a suite of very powerful toolkits (specialized libraries, for example for neural networks, signal processing or fuzzy logic) that can not be run with other software (it would be a license violation). The most famous is MATLAB, and let’s be frank, if MATLAB were free, it would be the numerical tool used by 99.9% of students. Here, we will discuss the pros and cons of MATLAB and its open source alternatives. The advantage of these environments is the ability to prototype a program faster and easily that in C, but at the cost of computing speed. But 30 years ago, the numerical computing environments were born. In old times, most numerical computing were done using common programming languages as Fortran, C/C++ or Basic. LibreOffice itself is an Office suite just like MS Office.Engineering and science students frequently do numerical computing and simulations as part of their research. English NUMERICAL METHODS KIT FOR MATLAB, SCILAB AND OCTAVE USERS This item: NUMERICAL METHODS KIT: FOR MATLAB, SCILAB AND OCTAVE USERS NUMERICAL. ODT format is just like a MS Word document but it is supported by LibreOffice Writer. This repository includes the manual in PDF and ODT formats. GitHub Link: Control Systems Lab Manual in Scilab Below are the links to the same file in two different formats: So this concludes my first formal blog post. To Matlab there are many free alternatives in competition, Scilab and Octave are the better known ones, but that list can be extended to many more, personally I would like to use Numerical Computation Libraries with C++ or Python (Python has great support too and is expanding python is in some sense spear-heading the use open source scientific software in academic circles and even in production setups where commercial licencing e.g. Matlab is quite expensive, and python provides a free alternative), but lets make python a topic for another day. (And surely we can pay back by getting involved in developing such projects and also by making donations). I like to argue: isn’t it better to use a free alternative that does the job equally well? Now I like this view way more than any other, the open source community has put tremendous effort in making all sorts of software, libraries, and other forms of digital goods, if you may, publicly available for free in some form or another. And students should not get into these messy legal issues directly or indirectly, students shouldn’t even pay single a rupee (a penny if that’s what you have) for their academic needs, but then let’s be a little realistic. Although I like this view myself, but let’s not debate on whether or not using a pirated copy is legal or not, the ethical or moral issues of piracy are mind boggling. Some will debate that it’s okay to use a pirated copy if not used for commercial purposes, and that when we do start using it, we will then buy a genuine copy. But hey, that didn’t turned out to be the case, and I believe Piracy is a global epidemic, so lets not talk about whether our institutions have genuine copies of proprietary software or not. The original manual was in Matlab, but it charges some fee even for students version though if my institution was offering us, students, the student version through some contract with mathworks, then I would have stayed silent and used a genuine copy of Matlab. I am sure you can find a lot of material on comparison between Matlab and other packages, but lets focus on the purpose of the manual that I am sharing. But this does not means that other packages are not coming close to Matlab’s performance. Matlab‘s heavy use in Control System Lab is no surprise, as it out performs many other contemporary competitors, in easy of use, amount of functionality, community support, detailed documentation, interfacing support for hardware and software and more. At our university we are by default adept at using Matlab for all our technical computation required by our courses. 2 Whats going on 3 Scilab developed since 1990 at INRIA / ENPC (France) open source 4 Demo Linear Algebra - basics (how to enter matrices etc.). The basic purpose for this write-up is share a Control System’s Lab Manual that I prepared, based upon the use of Scilab and its modelling and simulation package Xcos.
