This tutorial discusses how you can add your own simple functions to the Wolfram Language. As a first example, consider adding a function called f which squares its argument. The Wolfram …

f=(# ^2&) and f[n_]:=n^2 are two ways of defining a function, that for example give the same results for f[10]. Pure function definitions tend to be easier to combine with each other, but …

Jan 11, 2012 · This screencast demonstrates how to write simple functions in Mathematica and how compute values from them, differentiate them, and plot them.

4 days ago · A powerful tool of Mathematica is its ability to manipulate user-defined functions. This functions can be not only in terms of the internal build-in functions, but also in terms of …

Jun 5, 2020 · How can we construct functions like Mathematica does? For example, let's say that we want to create our own D function. The D function works like: In[1]:= D[x^2, x] Out[1]= 2 x ...

In the Wolfram Language a variable can not only stand for a value, but can also be used purely symbolically. And building on the Wolfram Language's powerful pattern language, "functions" …

Oct 23, 2013 · Defining a function with one variable in Mathematica, is by : f [x_]. How do I write a function for more variables?

Hints for working with variables, formatting, and defining functions. Tutorial for Mathematica & Wolfram Language.

The more Mathematica-like way of doing this is to actually return a function, rather than define a single global function as a side-effect: createFunction[a_] := Function[{x,y}, x …

The Wolfram Language lets you declare functions inline (called pure functions) to get around this. The most transparent way to define a pure function is with Function . The first argument is a …
