Module is a scoping construct that implements lexical scoping.Module constructs can be nested in any way, with inner variables being renamed if necessary.You can use Module as the right ‐hand side of a transformation rule with a condition attached.Symbols created by Module can be returned from modules.A Mathematica package provides one or more functions, which are placed into a context or group of Mathematica symbols. Typically, a package is placed in a file that has the extension '.m'. they won't change during the code execution. Stylistically, it is better to use With if you know that your variables are in fact constants, i.e. Module creates new symbols to represent each of its local variables every. What Is a Mathematica Package Introduction A Mathematica package is used to store Mathematica code so that it can be loaded into a Mathematica session. Module, OTOH, does generate temporary symbols (which are normal symbols with an attribute Temporary ), which can store a mutable state. Symbols created by Module carry the attribute Temporary. Module allows you to set up local variables with names that are local to the module. Before evaluating expr, Module substitutes new symbols for each of the local variables that appear anywhere in expr except as local variables in scoping constructs.The value of $ModuleNumber is incremented every time any module is used.The number nnn is the current value of $ModuleNumber. Module creates a symbol with name xxx$ nnn to represent a local variable with name xxx.A modulus is the number at which we start over when we are dealing with. The Wolfram Language has the most extensive collection of mathematical functions ever assembled. Module creates new symbols to represent each of its local variables every time it is called. In mathematics, this circular counting is called modular arithmetic, and the number 12 in this example is called a modulus. Since the Mathematica programming language (called the Wolfram language) is to a large extent a functional programming language, functions are the central objects here.Module allows you to set up local variables with names that are local to the module.
