Scilab: quick ref card

Scilab is an Open source software for numerical computing. website:

Scilab is very useful for engineering students and professionals.

It can handle data in matrix format.  Operations can be directly done on matrix. It can handle polynomials in one variable.

Here is the quick ref card for scilab : scilab- quick -sheet

R programming, Data Analysis and Data Mining


For statistical data handling,  data analysis, data visualization R-programming is one of the best  programming language. R is Free and  Open source Software. Here is the license details of R.

  • It has nice GUI like r-studio and many more.

Nice package for data analysis with  r -programming is shiny.

Companies are looking for making more business by analyzing customer data. Data mining is one the growing research area which is used by many industries. R programming rank first as a data mining tool. Read more on this blog.

Workshop on LaTeX , Scilab and SAGE

There was workshop on LaTeX, Scilab and SAGE in end of Nov.,12 at Abeda Inamdar College, Pune jointly organized by Dept. of Maths, University of Pune.

There were sessions on Maxima and GAP. SAGE, Maxima, GAP are very useful software for researchers in Mathematis.

Since  through SAGE one can use software like Maxima, Scilab, GAP  and many other scientific FOSS (Free Open source Software).

  •  Sage: Number Theory, Calculus,  Graphics, Symbolic computing, Linear Algebra, talks  by Prof. Mangal Narlikar,  Prof. Katre, Prof. Pingle, Prof. Siamwalla, Prof. AjitKumar, Mumbai and Manjusha Joshi, Pune.
  • Maxima: symbolic computation, true alternative to Mathematica, talks by Prof. Pawale, Mumbai Univeristy
  • GAP: Algebra, Group Theory, talk by Vikas Jadhav, BP, Pune
  • Scilab : Numerical Computations, talk by Prof. Katre, Prof. Pingle, Prfo. Madhu Belur, IITBombay and  Manjusha Joshi, Pune.
  • LaTeX: Scientific writing, talk by Manjusha Joshi and Prof. Pawale


These software supports exact calculations, Number theoretic calculations, algebraic calculations, graphs.

Image There is  a lot of material, documentation available on internet about these software. There were nice session on all these software. Lab was set up on Ubuntu linux. And participants enjoyed working on Linux as there was no problem of virus. 

Set up of local wiki was done so that participants can immediately get presentations and other documents on their pen drives. We conducted online LaTeX test with the help of moodle(  software. After end of the exam every one could see their performance.

The workshop arranged mainly for Maths college teachers and researchers from Pune university.

Thanks to Dept. of Maths, Pune Univeristy and Abeda Inamdar College for conducting such a wonderful workshop. Participants around 40.



SAGE: Open source Maths server online

In month of June, 2012, I went to Jalgao, Maharashtra, India for short term teachers program (STTP) to speak on Scilab ( and SAGE.

Installation of Scilab is easy and it was installed correctly so we did not had any problem for that session. Some of the participants were did very well. Scilab is basically for numerical computations and many toolboxes are available in scilab. Ideal for Engineering students.

At the time of SAGE, found that on many machines either it was not installed completely or taking lot of time to get open as installed on virtual box.

I wanted to start the session. I checked on online site. Since college had good internet speed, we started to work on online sage.

Around 40 participants worked at a time and we had the session on SAGE with out problem for 2 hours. Thanks to SAGE online service.




Lucknow Workshop

I went to Lucknow University for workshop on LaTeX and Scilab.
It was faculty training program. Participants are from North India.
They were very enthusiastic about learning, understanding and implementing Scilab.

The workshop took place in month of November, 2011.
As I heard, such type of workshop was arranged for the first time at that place.

We should conduct more workshops in northern part of India.
