Discussion Overview

The discussion revolves around the capabilities of MATLAB, specifically regarding its ability to perform symbolic manipulations using the Symbolic Math Toolbox (SMT). Participants explore the conditions under which MATLAB can solve equations symbolically and the limitations of the toolbox.

Discussion Character

  • Technical explanation, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant inquires whether MATLAB can solve long equations for 'x', acknowledging that other software like Mathematica may be better suited for symbolic notation.
  • Another participant confirms that MATLAB can perform symbolic manipulations if the Symbolic Math Toolbox is available.
  • A participant expresses interest in using the toolbox after learning about its capabilities.
  • Concerns are raised regarding the availability of SMT on different system architectures, noting that it is only available on 32-bit installations for Windows but available for 64-bit installations on Linux.
  • Another participant mentions that the Symbolic Math Toolbox does not recognize hyperbolic functions like cosh and sinh when simplifying equations.

Areas of Agreement / Disagreement

Participants generally agree that MATLAB can perform symbolic manipulations with the appropriate toolbox, but there are multiple views regarding its limitations and availability across different operating systems.

Contextual Notes

Limitations include the dependency of SMT on specific system architectures and the toolbox's inability to recognize certain mathematical functions during simplification.

For example: If I have some ridiculously long equation, and I want to solve it for 'x' can it do it?

I know that there are better software packages that can handle symbolic notation like Mathematica, but I would like for my output to be in the style of MATLAB.

If you have the Symbolic Math Toolbox, then yes.

Oooh...I think I just might!
 
Keep in mind that SMT is only available on 32bit installations of Matlab in the Windows environment, if you've got the 64bit variation installed, then congratulations you don't have SMT. Oddly enough SMT is available in 64bit Matlab for for the linux environment.

I just figured I'd throw out the heads up since I wasted a day trying to figure out why 'syms' wasn't recognized on my 64bit MATLAB install.
 
there is MATLAB for the linux environment? got have that...
 
Just for the record, Sym. Math Toolbox is not aware of cosh/sinh functions when simplifying equations. It can't see them.
