Level
(Built-in Mathematica Symbol) Level[expr, levelspec] gives a list of all subexpressions of expr on levels specified by levelspec. Level[expr, levelspec, f] applies f to the sequence of subexpressions.
LinearRecurrence[ker, init, n] gives the sequence of length n obtained by iterating the linear recurrence with kernel ker starting with initial values ...
ListContourPlot3D[array] generates a contour plot from a three-dimensional array of values. ListContourPlot3D[{{x_1, y_1, z_1, f_1}, {x_2, y_2, z_2, f_2}, ...}] generates a ...
LogIntegral[z] is the logarithmic integral function li(z).
Min
(Built-in Mathematica Symbol) Min[x_1, x_2, ...] yields the numerically smallest of the x_i. Min[{x_1, x_2, ...}, {y_1, ...}, ...] yields the smallest element of any of the lists.
Quotient[m, n] gives the integer quotient of m and n. Quotient[m, n, d] uses an offset d.
RootLocusPlot[g, {k, k_min, k_max}] generates the root locus plot of a rational function g of k ranging from k_min to k_max.RootLocusPlot[sys, ...] plots the root loci of a ...
SetAccuracy[expr, a] yields a version of expr in which all numbers have been set to have accuracy a.
Sow
(Built-in Mathematica Symbol) Sow[e] specifies that e should be collected by the nearest enclosing Reap. Sow[e, tag] specifies that e should be collected by the nearest enclosing Reap whose pattern ...
Split
(Built-in Mathematica Symbol) Split[list] splits list into sublists consisting of runs of identical elements. Split[list, test] treats pairs of adjacent elements as identical whenever applying the ...
