Switch in Mathematica resembles Switch in C, but differs from it significantly.
Which is essentially a replacement for nested If statements. Operators Which and Switch These operators generalize If to situations where we have to switch between several possibilities. The condition is checked, we conclude that If uses non-standard Since normally the arguments of the function are evaluated before theįunction itself, while in the case of If the operator whichĬorresponds to True of False branch should only be evaluated after In which case nothing is done for the False outcome (Null is If it evaluates to True, the first operator oper1 isĮvaluated, otherwise a second one. The condition should in principle evaluate to True or False, in order for If to makeĪ choice. The If operator has the following syntax : If Here is a condition being tested. As you can see, the short-hand notation is the same as in C. We will consider logical AND : short-hand &, literal equivalent And, logical OR: short-hand ||, literal equivalent Or, and the negation NOT (short-hand Return to the main page for the course APMA0340Īs many other languages, Mathematica has several built-in logical operators.
