when asking for help about solve or syms command, MATLAB returns solve not found, or syms not found. Probably the Symbolic Math function toolbox is not working. Reinstalling MATLAB R2009a, doesn't solve the problem.

Yes, and all other programs including simulations are working well.

You either have not installed the Symbolic Toolbox, or you do not have a license for it, or it is not on your MATLAB path.
Use
which -all solve
to see if you have the solve routine but there is no license for it (it will say "no license")
Use
ver
to determine which toolkits you have installed.
Note: The Symbolic Toolbox license is included with MATLAB Student Version, but the toolbox is not installed by default. For the Academic and Professional licenses, the Symbolic Toolbox license is not included and must be purchased.

Go to
Help -> Product Help
Try to find the documentation of syms and solve commands. If they do not show up, obviously there was a problem during the installation and they are not present on your system.
I am assuming the corresponding tool-box has been installed. Even when you can not get the help for solve and syms, can you use them in your command line?
