FreeQ (Built-in Mathematica Symbol)

FreeQ[expr, form] yields True if no subexpression in expr matches form, and yields False otherwise. FreeQ[expr, form, levelspec] tests only those parts of expr on levels ...

Bitwise Operations (Mathematica Guide)

Mathematica can represent bit vectors of arbitrary length as integers, and uses highly optimized algorithms—including several original to Wolfram Research—to perform bitwise ...

Remote Definitions (Parallel Package Tutorial)

Parallel kernels do not have access to the values of variables defined in the master kernel, nor do they have access to locally defined functions. Mathematica contains a ...

ToDiscreteTimeModel (Built-in Mathematica Symbol)
