NevilleThetaN[z, m] gives the Neville theta function \[CurlyTheta]_n (z \[VerticalSeparator] m).
NevilleThetaS[z, m] gives the Neville theta function \[CurlyTheta]_s (z \[VerticalSeparator] m).
Normal
(Built-in Mathematica Symbol) Normal[expr] converts expr to a normal expression, from a variety of special forms.
NumericQ[expr] gives True if expr is a numeric quantity, and False otherwise.
OpenerView[{expr_1, expr_2}] represents an object which displays as an opener, together with expr_1 if the opener is closed, and both expr_1 and expr_2 if it is ...
QRDecomposition[m] yields the QR decomposition for a numerical matrix m. The result is a list {q, r}, where q is an orthogonal matrix and r is an upper-triangular matrix.
Rationalize[x] converts an approximate number x to a nearby rational with small denominator. Rationalize[x, dx] yields the rational number with smallest denominator that lies ...
RescalingTransform[{{x_min, x_max}, {y_min, y_max}, ...}, {{xp_min, xp_max}, ...}] gives a TransformationFunction that rescales the region with coordinate ranges x_min to ...
RGBColor[red, green, blue] is a graphics directive specifying that objects that follow are to be displayed, if possible, in the color given. RGBColor[r, g, b, a] specifies ...
RootReduce[expr] attempts to reduce expr to a single Root object.
