Hello,

I'd like to know if there's a way in MATLAB to solve a symbolic system of equations with symbolic coefficients ?

Thanks for your help.

Yes, the symbolic math toolbox will do this. Type mupad at the matlab command prompt, then dig into the help files and documentation to find your feet.

Overview and examples here:

I tried the example http://www.mathworks.com/help/symbolic/linsolve.html on my Matlab and it generates this error message : "??? Undefined function or method 'linsolve' for input arguments of type 'sym'.".

I guess this is due to the old version of Matlab I am running (R2009b).

It looks like I got the answer to my question.

Thank you guys for your answers.
