GraphicsColumn[{g_1, g_2, ...}] generates a graphic in which the g_i are laid out in a column, with g_1 above g_2, etc. GraphicsColumn[list, alignment] aligns each element ...
GraphicsRow[{g_1, g_2, ...}] generates a graphic in which the g_i are laid out in a row.GraphicsRow[list, spacing] leaves the specified spacing between successive elements.
Inner
(Built-in Mathematica Symbol) Inner[f, list_1, list_2, g] is a generalization of Dot in which f plays the role of multiplication and g of addition.
IntegerDigits[n] gives a list of the decimal digits in the integer n. IntegerDigits[n, b] gives a list of the base b digits in the integer n. IntegerDigits[n, b, len] pads ...
InterpolatingFunction[domain, table] represents an approximate function whose values are found by interpolation.
Item
(Built-in Mathematica Symbol) Item[expr, options] represents an item within constructs such as Grid, Overlay, and Manipulate that displays with expr as the content, and with the specified options applied ...
LatticeReduce[{v_1, v_2, ...}] gives a reduced basis for the set of vectors v_i.
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 ...
NullSpace[m] gives a list of vectors that forms a basis for the null space of the matrix m.
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.
