Naming and Finding Files (Mathematica Tutorial)

The precise details of the naming of files differ from one computer system to another. Nevertheless, Mathematica provides some fairly general mechanisms that work on all ...

Initialization (Built-in Mathematica Symbol)

Initialization is an option for Dynamic, DynamicModule, Manipulate, and related constructs that specifies an expression to be evaluated when the construct is first used or ...

Pause (Built-in Mathematica Symbol)

Pause[n] pauses for at least n seconds.

SortBy (Built-in Mathematica Symbol)

SortBy[list, f] sorts the elements of list in the order defined by applying f to each of them.

Polynomial Orderings (Mathematica Tutorial)

The leading term of a polynomial can be chosen in many different ways. For multivariate polynomials, sorting by the total degree of the monomials is often useful. Different ...

VectorDensityPlot (Built-in Mathematica Symbol)

VectorDensityPlot[{{v_x, v_y}, s}, {x, x_min, x_max}, {y, y_min, y_max}] generates a vector plot of the vector field {v_x, v_y} as a function of x and y, superimposed on a ...

Expectation (Built-in Mathematica Symbol)

Expectation[expr, x \[Distributed] dist] gives the expectation of expr under the assumption that x follows the probability distribution dist. Expectation[expr, x ...

StreamDensityPlot (Built-in Mathematica Symbol)

StreamDensityPlot[{{v_x, v_y}, s}, {x, x_min, x_max}, {y, y_min, y_max}] generates a stream plot of the vector field {v_x, v_y} as a function of x and y, superimposed on a ...

AbsoluteTiming (Built-in Mathematica Symbol)

AbsoluteTiming[expr] evaluates expr, returning a list of the absolute number of seconds in real time that have elapsed, together with the result obtained.

DynamicSetting (Built-in Mathematica Symbol)

DynamicSetting[e] represents an object which displays as e, but is interpreted as the dynamically updated current value of Setting[e] if supplied as Mathematica ...
