LibraryFunctionInformation (Built-in Mathematica Symbol)

LibraryFunctionInformation[fun] returns information about a LibraryFunction.

Low-Level System Spelunking (Mathematica Guide)

Mathematica is a large and complex software system. Although strongly not supported for production purposes, it is sometimes instructive to "spelunk" in the system, looking ...

DifferentialRoot (Built-in Mathematica Symbol)

DifferentialRoot[lde] represents a function that solves the linear differential equation specified by lde[y, x].

LibraryFunctionError (Built-in Mathematica Symbol)

LibraryFunctionError[name, code] represents an error returned from a LibraryFunction.

SetDelayed (Built-in Mathematica Symbol)

lhs := rhs assigns rhs to be the delayed value of lhs. rhs is maintained in an unevaluated form. When lhs appears, it is replaced by rhs, evaluated afresh each time.

Compute a Limit (Mathematica How To)

Even simple-looking limits are sometimes quite complicated to compute. Mathematica provides functionality to evaluate several kinds of limits.

Mathematica Packages (Mathematica Tutorial)

One of the most important features of Mathematica is that it is an extensible system. There is a certain amount of mathematical and other functionality that is built into ...

Piecewise (Built-in Mathematica Symbol)

Piecewise[{{val_1, cond_1}, {val_2, cond_2}, ...}] represents a piecewise function with values val_i in the regions defined by the conditions cond_i. Piecewise[{{val_1, ...

Functions with Sensitive Dependence on ... (Mathematica Tutorial)

Functions that are specified by simple algebraic formulas tend to be such that when their input is changed only slightly, their output also changes only slightly. But ...

CurrentValue (Built-in Mathematica Symbol)

CurrentValue[item] gives the current value of item at a location in the Mathematica system and interface. CurrentValue[{item, spec}] gives the current value for the feature ...
