Throw
(Built-in Mathematica Symbol) Throw[value] stops evaluation and returns value as the value of the nearest enclosing Catch. Throw[value, tag] is caught only by Catch[expr, form] where form is a pattern ...
RuntimeOptions is an option for Compile that specifies runtime settings for the compiled function it creates.
CellGroup[{cell_1, cell_2, ...}] gives an open group of cells that can appear in a Mathematica notebook.CellGroup[{cell_1, cell_2, ...}, 1] gives a cell group in which only ...
VertexRenderingFunction is an option for GraphPlot and related functions that gives a function to generate the graphics primitives to use in rendering each vertex.
RegionPlot[pred, {x, x_min, x_max}, {y, y_min, y_max}] makes a plot showing the region in which pred is True.
StandardForm[expr] prints as the standard Mathematica two-dimensional representation of expr.
In many computations you are concerned only with the final result of evaluating the expression given as input. But sometimes you also want to collect expressions that were ...
Timing
(Built-in Mathematica Symbol) Timing[expr] evaluates expr, and returns a list of the time in seconds used, together with the result obtained.
Flatten
(Built-in Mathematica Symbol) Flatten[list] flattens out nested lists. Flatten[list, n] flattens to level n. Flatten[list, n, h] flattens subexpressions with head h. Flatten[list, {{s_11, s_12, ...}, ...
