When working in Mathematica , you will often find it useful to view groups of functions that relate to a specific subject area or set of tasks. The Documentation Center ...

Pure functions. When you use functional operations such as Nest and Map, you always have to specify a function to apply. In all the examples above, we have used the "name" of ...

Long used in its simplest form in mathematics, functional iteration is an elegant way to represent repeated operations. Mathematica's symbolic architecture makes powerful ...

Turning conditions into numbers. Boole[expr] is a basic function that turns True and False into 1 and 0. It is sometimes known as the characteristic function or indicator ...

The ability to define and use your own functions is part of what gives Mathematica such power. It is often inconvenient to have to explicitly name a function for every small ...

"Defining Functions" discusses how you can define functions in Mathematica. In a typical case, you would type in f[x_]=x^2 to define a function f. (Actually, the definitions ...

DefineDLLFunction["func", " dll", rtype, atypes] returns a Mathematica function that calls the specified function func with argument types atypes and return type rtype in the ...

Mathematica can plot parametric functions in both two and three dimensions. Use a parametric plot when you can express the x and y or x , y , and z coordinates at each point ...

Mathematica contains the world's largest collection of number theoretic functions, many based on specially developed algorithms.

$DisplayFunction gives the default setting for the option DisplayFunction in graphics functions.
