MaxMixtureKernels is an option for SmoothKernelDistribution and related functions that specifies the maximum number and location of kernel functions to use in the estimation.
MaxPlotPoints is an option for plotting functions like ArrayPlot and ListPlot3D that specifies the maximum number of points that will explicitly be included in the output.
None
(Built-in Mathematica Symbol) None is a setting used for certain options.
NRoots
(Built-in Mathematica Symbol) NRoots[lhs == rhs, var] yields a disjunction of equations which represent numerical approximations to the roots of a polynomial equation.
NullRecords is an option for Read and related functions which specifies whether null records should be taken to exist between repeated record separators.
NyquistGridLines is an option to NyquistPlot that specifies contours of constant magnitude and phase of a closed-loop system.
Overlay
(Built-in Mathematica Symbol) Overlay[{expr_1, expr_2, ...}] displays as an overlay of all the expr_i.Overlay[{expr_1, expr_2, ...}, {i, j, ...}] displays as an overlay of expr_i, expr_j, ...
Padding
(Built-in Mathematica Symbol) Padding is an option to various array and image operations that specifies what padding to use when extending beyond the original data specified.
PlayRange is an option for Play and related functions which specifies what range of sound amplitude levels should be included.
PolynomialQ[expr, var] yields True if expr is a polynomial in var, and yields False otherwise. PolynomialQ[expr, {var_1, ...}] tests whether expr is a polynomial in the var_i.
