SUMMARY

The discussion identifies several free alternatives to MATLAB for simulating equations, particularly the Convection Diffusion Equation. Key tools mentioned include Python with Matplotlib for 2D graphing, Octave combined with Gnuplot, and FreeMat as a MATLAB-like environment. Scilab is also noted as a potential option, alongside other software like Euler and Maxima available for Ubuntu users. All suggested tools are free to download and use, catering to users seeking cost-effective solutions for scientific simulations.

PREREQUISITES
  • Familiarity with Python programming and Matplotlib library
  • Basic understanding of Octave and Gnuplot integration
  • Knowledge of FreeMat as a MATLAB alternative
  • Experience with Ubuntu software installation and management
NEXT STEPS
  • Explore Python's Matplotlib for advanced graphing techniques
  • Research Octave and Gnuplot for enhanced simulation capabilities
  • Investigate FreeMat features and its compatibility with MATLAB scripts
  • Learn about Scilab's functionalities for solving differential equations
USEFUL FOR

This discussion is beneficial for students, researchers, and developers looking for free software alternatives to MATLAB for equation simulation and graphing, particularly in scientific and educational contexts.

¿Software to simulate graphs?

Is there an alternative to MATLAB for simulating equations,

I am looking for a way of getting some intuition for some Convection Diffusion Equation. I would like to play around with it, simulate it, change its IC/BCs, having some interactive graphs and stuff.

There are many choices.

There is python and the matplotlib (2D mostly).
There is octave/gnuplot combination
There is freemat (intended to be a free a-la-matlab environment)
Possibly Scilab...have not used it, but have heard good things about it.
and a few other choices that are ready to download in my Ubuntu machine: Euler, Maxima, etc. (just go to software downloads and filter for Scientific or Educational software).

these are all free (as in gratis) choices...I presume that's what you were looking for.
