Parts of Expressions (Mathematica Tutorial)

Since lists are just a particular kind of expression, it will come as no surprise that you can refer to parts of any expression much as you refer to parts of a list. This ...

ArrayRules (Built-in Mathematica Symbol)

ArrayRules[SparseArray[...]] gives the rules {pos_1 -> val_1, pos_2 -> val_2, ...} specifying elements in a sparse array. ArrayRules[list] gives rules for SparseArray[list].

SplitBy (Built-in Mathematica Symbol)

SplitBy[list, f] splits list into sublists consisting of runs of successive elements that give the same value when f is applied.SplitBy[list, {f_1, f_2, ...}] recursively ...

ChartElementFunction (Built-in Mathematica Symbol)

ChartElementFunction is an option for charting functions such as BarChart that gives a function to use to generate the primitives for rendering each chart element.

ArrayPlot (Built-in Mathematica Symbol)

ArrayPlot[array] generates a plot in which the values in an array are shown in a discrete array of squares.

SMILES (.smi) (Mathematica Import/Export Format)

MIME type: chemical/x-daylight-smiles SMILES chemical format. Commonly used to describe the structure of chemical molecules. SMILES is an acronym for Simplified Molecular ...

Map a Function over a List (Mathematica How To)

Mathematica includes many powerful operations for working with lists. It is often desirable to map a function onto each individual element in a list. While listable functions ...

CopyFile (Built-in Mathematica Symbol)

CopyFile["file_1", "file_2"] copies file_1 to file_2.

Take (Built-in Mathematica Symbol)

Take[list, n] gives the first n elements of list. Take[list, -n] gives the last n elements of list. Take[list, {m, n}] gives elements m through n of list. Take[list, seq_1, ...
