A Basic Introduction on Math-Link in Mathematica

Starting from the basic ideas of mathematica, we give a detailed description about the way of linking of external programs with mathematica through proper mathlink commands. This article may be quite helpful for the beginners to start with and write programs in mathematica. In the first part, we illustrate how to use a mathemtica notebook and write a complete program in the notebook. Following with this, we also mention elaborately about the utility of the local and global variables those are very essential for writing a program in mathematica. All the commands needed for doing different mathematical operations can be found with some proper examples in the mathematica book written by Stephen Wolfram \cite{wolfram}. In the rest of this article, we concentrate our study on the most significant issue which is the process of linking of {\em external programs} with mathematica, so-called the mathlink operation. By using proper mathlink commands one can run very tedious jobs efficiently and the operations become extremely fast.Comment: 14 pages, 2 figure

How to Run Mathematica Batch-files in Background ?

Mathematica is a versatile equipment for doing numeric and symbolic computations and it has wide spread applications in all branches of science. Mathematica has a complete consistency to design it at every stage that gives it multilevel capability and helps advanced usage evolve naturally. Mathematica functions work for any precision of number and it can be easily computed with symbols, represented graphically to get the best answer. Mathematica is a robust software development that can be used in any popular operating systems and it can be communicated with external programs by using proper mathlink commands. Sometimes it is quite desirable to run jobs in background of a computer which can take considerable amount of time to finish, and this allows us to do work on other tasks, while keeping the jobs running. Most of us are very familiar to run jobs in background for the programs written in the languages like C, C++, F77, F90, F95, etc. But the way of running jobs, written in a mathematica notebook, in background is quite different from the conventional method. In this article, we explore how to create a mathematica batch-file from a mathematica notebook and run it in background. Here we concentrate our study only for the Unix version, but one can run mathematica programs in background for the Windows version as well by using proper mathematica batch-file.Comment: 7 pages, 1 figur

Parallel Evaluation of Mathematica Programs in Remote Computers Available in Network

Mathematica is a powerful application package for doing mathematics and is used almost in all branches of science. It has widespread applications ranging from quantum computation, statistical analysis, number theory, zoology, astronomy, and many more. Mathematica gives a rich set of programming extensions to its end-user language, and it permits us to write programs in procedural, functional, or logic (rule-based) style, or a mixture of all three. For tasks requiring interfaces to the external environment, mathematica provides mathlink, which allows us to communicate mathematica programs with external programs written in C, C++, F77, F90, F95, Java, or other languages. It has also extensive capabilities for editing graphics, equations, text, etc. In this article, we explore the basic mechanisms of parallelization of a mathematica program by sharing different parts of the program into all other computers available in the network. Doing the parallelization, we can perform large computational operations within a very short period of time, and therefore, the efficiency of the numerical works can be achieved. Parallel computation supports any version of mathematica and it also works as well even if different versions of mathematica are installed in different computers. The whole operation can run under any supported operating system like Unix, Windows, Macintosh, etc. Here we focus our study only for the Unix based operating system, but this method works as well for all other cases.Comment: 10 pages, 1 figure. arXiv admin note: substantial text overlap with arXiv:cs/060509
