For some reason I cannot use the command "syms"

This is what comes up when I try to use it.

---------------------------------------------------
>> syms s;
??? Undefined function or method 'syms' for input arguments of type
'char'.

>> help syms

syms not found.

Use the Help browser Search tab to search the documentation, or
type "help help" for help command options, such as help for methods.
----------------------------------------------------------

What is wrong? Am I not loading something that allows this to function? Nobody I have talked to has been able to tell me why it won't work.

Type the command 'ver' and see if you have the symbolic toolbox installed

SYMS is a function in Symbolic Math Toolbox. If you do not have this
toolbox installed or cannot check out a license for it, you will not be able
to use SYMS. You can check if you have this toolbox installed using the VER
function; if you have it installed, check with the administrator for your
license to determine if all the licenses for this toolbox are checked out.
