hi, i need to switch to matlab to solve some symbolic problems. i have the symbolic math toolbox installed. i even unistalled and installed again but nothing helps to make it working. when i just simply do syms x - i get this error (below)- maybe missing something in my installation? any idea? i have windows 7
Error using sym (line 186)

Hi Lucie
The error message is received because the 'syms' function from the Symbolic Math Toolbox is shadowed by the 'syms' function from Maple Soft. To resolve this issue execute the following commands at the MATLAB command prompt.
>> restoredefaultpath
>> savepath
Hope the above information helped you.
Thanks
Santhosh
