Relational operators compare valueA and valueB and return 1 if the test is
true or 0 if the test is false. valueA and valueB can be real numbers,
expressions, or lists. For = and ƒ only, valueA and valueB also can be
matrices or complex numbers. If valueA and valueB are matrices, both
must have the same dimensions.
Relational operators are often used in programs to control program flow
and in graphing to control the graph of a function over specific values.
