Open source or free alternatives to MathCad

Click For Summary

Discussion Overview

The discussion revolves around seeking free or low-cost alternatives to MathCad for performing mathematical tasks such as solving differential equations, integration, and creating 3D plots. Participants share their experiences and recommendations for software that can assist in checking work without the expense of commercial programs.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant mentions using MathCad as an example and expresses a need for software that can provide solutions for verification without high costs.
  • Another participant suggests GNU Octave as a free alternative to Matlab, noting its use in universities and similarity in commands and syntax.
  • A request for a good graphical user interface (GUI) for Octave on Windows systems is made, indicating a preference for using a more powerful desktop.
  • XOctave is recommended as a front end for GNU Octave, which is available for Windows.
  • One participant discusses the capabilities of Octave for numeric tasks and suggests GNU Maxima for symbolic integration and arbitrary precision arithmetic.
  • wxmaxima is mentioned as a nice front-end for Maxima, and Sage is noted for its integration with LaTeX, although it is said to have limitations in 3D graphing.

Areas of Agreement / Disagreement

Participants generally agree on the utility of GNU Octave and GNU Maxima as alternatives to MathCad, but there are varying opinions on the effectiveness of the graphical interfaces and the capabilities of the software mentioned.

Contextual Notes

Some participants express uncertainty about the full capabilities of MathCad, and there are mentions of limitations regarding the graphical output of certain software options.

Who May Find This Useful

This discussion may be useful for students or professionals seeking affordable software solutions for mathematical computations and visualizations, particularly those who are familiar with or transitioning from MathCad.

I am just using MathCad as an example, as I don't know others. In college I did use something that did good 3D plots, and solved differential equations and performed integration.

I was wondering if there were free or low-cost alternatives to these expensive programs. I just need something that can give me a solution to check my work against.

I tend to have a problem of knowing when to stop deriving. I'll work on a problem, and wonder if I really have the solution.

Since I don't have $100's to purchase something that probably does way more than I need, I'm wondering what other software will be suitable.

Thanks.

There's a GNU "version" of Matlab called Octave that is used in universities. Most of the commands and syntax are the same.
 
Thanks. Can you also recommend a good GUI for Octave? I'm on a Windows system. I have Windows XP x64 and Windows Vista, on two separate systems.

But I'll probably use my Windows x64 desktop because it's more powerful.
 
XOctave
Its just a front end, GNU Octave must be installed. It is available for Windows and it is pretty slick.
 
I just looked at the MathCad web page - it was clearly designed by business/marketing types so I do not know all the capabilities of mathcad.

for the numeric stuff, Octave mentioned above is great. Doesn't have beautiful plots but they are functional ...

If you do symbolic integration or other symbolic work, I would recommend gnu maxima. It also does arbitrary precision arithmetic if you are ever interested.

wxmaxima provides a very nice front-end to maxima.
note that sage will integrate with latex very easily (3d graphing is a bit weak, however)
