HoldComplete (Built-in Mathematica Symbol)

HoldComplete[expr] shields expr completely from the standard Mathematica evaluation process, preventing even upvalues associated with expr from being used.

ToUpperCase (Built-in Mathematica Symbol)

ToUpperCase[string] yields a string in which all letters have been converted to uppercase.

Power (Built-in Mathematica Symbol)

x^y gives x to the power y.

TreeForm (Built-in Mathematica Symbol)

TreeForm[expr] displays expr as a tree with different levels at different depths. TreeForm[expr, n] displays expr as a tree only down to level n.

Create a Matrix (Mathematica How To)

Matrices are represented in Mathematica with lists. They can be entered directly with the { } notation, constructed from a formula, or imported from a data file. Mathematica ...

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].

And (Built-in Mathematica Symbol)

e_1 && e_2 && ... is the logical AND function. It evaluates its arguments in order, giving False immediately if any of them are False, and True if they are all True.

HoldAll (Built-in Mathematica Symbol)

HoldAll is an attribute which specifies that all arguments to a function are to be maintained in an unevaluated form.

Or (Built-in Mathematica Symbol)

e_1 || e_2 || ... is the logical OR function. It evaluates its arguments in order, giving True immediately if any of them are True, and False if they are all False.
