Usage
Finds the symbolic variables in an expression. The syntax for its
use is
syms = symvar(expr)
where expr is a string containing an expression, such as
'x^2 + cos(t+alpha)'. The result is a cell array of strings
containing the non-function identifiers in the expression. Because
they are usually not used as identifiers in expressions, the strings
'pi','inf','nan','eps','i','j' are ignored.
