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 ...
The functions FindMinimum, FindMaximum, and FindRoot have the HoldAll attribute and so have special semantics for evaluation of their arguments. First, the variables are ...
SplineWeights is an option for B-spline functions and graphics primitives that specifies weights of control points.
A method like "Newton's" method chooses a step, but the validity of that step only goes as far as the Newton quadratic model for the function really reflects the function. ...
DelaunayTriangulationQ[{{x_1, y_1}, {x_2, y_2}, ...}, val] gives True if the triangulation of the points {{x_1, y_1}, ...} represented by the vertex adjacency list val is a ...
MaxMixtureKernels is an option for SmoothKernelDistribution and related functions that specifies the maximum number and location of kernel functions to use in the estimation.
The GUIKit framework makes it relatively easy to reuse interface definitions because of its automatic use of private symbol contexts for each instance of a definition. There ...
LogicalExpand[expr] expands out logical combinations of equations, inequalities, and other functions.
NumberQ
(Built-in Mathematica Symbol) NumberQ[expr] gives True if expr is a number, and False otherwise.
