Error while using syms in matlab

I am a beginner to the Matlab and currently using Matlab7. I tried with the basic example of solving a polynomial equation.

syms x
y=x^2+1;
solve(y)

When I run the program,I get some error in command files like

   ??? Attempt to execute SCRIPT class as a function.

Error in ==> sym.sym>char2sym at 385
      S = class(struct('s',x),'sym');

Error in ==> sym.sym at 92
   S = char2sym(x);

Error in ==> syms at 74
      assignin('caller',x,sym(x));

Error in ==> solve at 1
syms x

Anyone who could help me with it?? I don't even understand the error message.

Which is the current folder? The parent folder of class.m, which contains the documentation only? Then change the current directory, e.g.:

cd(tempdir)

and run the code again.

Or did you create a script called "class.m" by your own? If so: Don't do this.

Just a suggestion: could it also be an incompatibility? Matlab 7 is from 2004. That's quite a list of release notes to go through...

It is better to get a much newer Matlab version. Faster, more options, less (or at least other) bugs, etc.

Thank you so much @Jan simon. It worked. I'd been scratching my head for days and finally it worked. :) :)
