TextClipboardType (Built-in Mathematica Symbol)

TextClipboardType is an option for cells that specifies how Edit \[FilledRightTriangle] Copy treats a cell when converting it for the system's textual clipboard.

UpSet (Built-in Mathematica Symbol)

lhs ^= rhs assigns rhs to be the value of lhs, and associates the assignment with symbols that occur at level one in lhs.

Manipulating Elements of Lists (Mathematica Tutorial)

Many of the most powerful list manipulation operations in Mathematica treat whole lists as single objects. Sometimes, however, you need to pick out or set individual elements ...

Simplifying with Assumptions (Mathematica Tutorial)

Simplifying with assumptions. Mathematica does not automatically simplify this, since it is only true for some values of x. Sqrt[x^2] is equal to x for x≥0, but not otherwise.

Set (Built-in Mathematica Symbol)

lhs = rhs evaluates rhs and assigns the result to be the value of lhs. From then on, lhs is replaced by rhs whenever it appears. {l_1, l_2, ...} = {r_1, r_2, ...} evaluates ...

MapAt (Built-in Mathematica Symbol)

MapAt[f, expr, n] applies f to the element at position n in expr. If n is negative, the position is counted from the end. MapAt[f, expr, {i, j, ...}] applies f to the part of ...

ToBoxes (Built-in Mathematica Symbol)

ToBoxes[expr] generates boxes corresponding to the printed form of expr in StandardForm. ToBoxes[expr, form] gives the boxes corresponding to output in the specified form.

Det (Built-in Mathematica Symbol)

Det[m] gives the determinant of the square matrix m.

CanberraDistance (Built-in Mathematica Symbol)

CanberraDistance[u, v] gives the Canberra distance between vectors u and v.

LeafCount (Built-in Mathematica Symbol)

LeafCount[expr] gives the total number of indivisible subexpressions in expr.
