Scilab is one of the oldest Matlab-like tools.
FREEMAT TRANSFER FUNCTIONS HOW TO
I won't be comparing or contrasting the tools rather, I'll briefly present them with some pointers on how to install and use the tool, and I'll leave the final determination of which tool is "better" for your case up to you. For parallel code execution, you usually need some add-ons, such as Message Passing Interface (MPI), and a code rewrite to allow multiple instances of the tool on different nodes that communicate over a network.
FREEMAT TRANSFER FUNCTIONS SERIAL
Serial in this case means that the vast majority of the code is executed on a single core, although some of the programs have the ability to do a small amount of parallel execution. They have varying degrees of success with Matlab compatibility, and all are inherently serial applications. These tools try to be as close as possible to Matlab syntax so that Matlab code will transfer over easily, with the possible exception of Simulink and Matlab GUI code.
A whole host of other tools exists if you want to stray from Matlab compatibility even further, such as R or SciPy however in this article, I will talk about the open source tools Scilab, GNU Octave, and FreeMat. When people ask what tools or applications they can try on their shiny new cluster, I tend to recommend one of these Matlab-like tools, even though they aren't strictly parallel right out of the box (so to speak).Ī few tools that are somewhat Matlab-like – some still surviving and some defunct – include RLaB, RLaB+, JMathlab, and O-Matrix (commercial). This brings up the category of tools typically called "Matlab-like" that is, they try to emulate the concept of Matlab with compatible syntax so that moving back and forth is relatively easy. I don't want to take anything away from MathWorks, the creator of Matlab, because their product is a wonderful application, but for a number of reasons, Matlab might not be the answer for some people (e.g., they can't afford Matlab or can't afford 25,000 licenses, they just want to try a few Matlab features, or they want or need access to the source code). Needless to say, Matlab is used very heavily at a number of places, so it is a very good candidate for running on an HPC system. Some researchers use it for parameter sweeps by launching 25,000 or more individual Matlab runs at the same time.
People are using Matlab for a variety of tasks that range from the humanities, to science, to engineering, to games, and more. For example, a fairly recent blog posting from Harvard University's Faculty of Arts and Sciences, Research Computing Group showed that the second most popular Environment Module was Matlab. One of the most popular applications is Matlab, which many people use in their everyday work and research – either Matlab or Matlab-like tools. A common question from people who build both large and small HPC clusters is, "What applications can I run on my HPC system?"
