Hi all

I'm trying to install the Maple toolbox for MATLAB on Windows XP with MATLAB 2010a. The toolbox seemed to install fine (in MATLABROOT/toolbox/maple), but when I open MATLAB and run the following commands I get the following results:

>> syms x
??? Undefined function or method 'sym' for input arguments of type 'char'.

Error in ==> syms at 47
assignin('caller',varargin{1},sym(varargin{1}));

>> which sym -all
C:\Program Files\MATLAB\R2010a\toolbox\maple\@sym\sym.m % sym constructor, Has no license available

Does anyone know how this can be fixed?

Thanks,
Oliver

The default engine for symbolic calculations is MuPAD. I suspect you
need to map yours to Maple, perhaps using symengine?

Thanks for answering, Loren. I don't have MATLAB's own symbolic toolbox, so there is no default symbolic engine and no symengine function. The "Maple toolbox for MATLAB" is a product by Maplesoft which aims to be a replacement for that toolbox, incorporating all the important functions. I don't think it needs MATLAB to have a concept of the symbolic engine. I have the Maple toolbox working fine with MATLAB 2009b on my Linux machine.

Is there some strange behaviour when placing non-MATLAB toolboxes in the MATLABROOT/toolbox directory under Windows or MATLAB 2010a?

The problem went away when I updated the toolbox from v12 to v12.01.
