NevilleThetaC[z, m] gives the Neville theta function \[CurlyTheta]_c (z \[VerticalSeparator] m).
ParabolicCylinderD[\[Nu], z] gives the parabolic cylinder function D_\[Nu] (z).
PartitionsQ[n] gives the number q (n) of partitions of the integer n into distinct parts.
PasteButton[expr] represents a button that pastes expr whenever it is pressed. PasteButton[label, expr] displays with label on the button.
PiecewiseExpand[expr] expands nested piecewise functions in expr to give a single piecewise function. PiecewiseExpand[expr, assum] expands piecewise functions using ...
PrimeQ
(Built-in Mathematica Symbol) PrimeQ[expr] yields True if expr is a prime number, and yields False otherwise.
QPolyGamma[z, q] gives the q-digamma function \[Psi]_q (z).QPolyGamma[n, z, q] gives the n\[Null]^th derivative of the q-digamma function \[Psi]_q^(n)(z).
Range
(Built-in Mathematica Symbol) Range[i_max] generates the list {1, 2, ..., i_max}. Range[i_min, i_max] generates the list {i_min, ..., i_max}. Range[i_min, i_max, di] uses step di.
ReflectionMatrix[v] gives the matrix that represents reflection of points in a mirror normal to the vector v.
Round
(Built-in Mathematica Symbol) Round[x] gives the integer closest to x. Round[x, a] rounds to the nearest multiple of a.
