SYM and SYMS are essentially the same; SYMS is often used in the command
form, while SYM is often used in the function form. For instance, the
following two commands do essentially the same thing, though for other
reasons I recommend using the first form.

x = sym('x');
syms x;

VPA is a _method_ for symbolic objects created by SYM or SYMS that displays
them using variable-precision arithmetic.

For more information, read:

    help sym
    help syms
    help vpa
