To define a variable which I want to keep as a variable I always used this script:

syms X1 X2

But now I installed a newer version of Matlab (R2008b), and it gives an error when I try to define X1 & X2 does anybody know what script to use?

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

Error in ==> opdr224 at 4
syms X1 X2

I hope anyone can help me!

Thanks

If you actually do have the symbolic TB in your new
release, it may not be installed correctly. Does matlab
think you have it? Look at the output of ver in MATLAB.

ver

Then check your search path.
