412 Functions and commands

quartiles Returns the minimum, first quartile, median, third quartile, and

maximum of the elements of a list or the columns of a matrix.

quartiles(Lst||Mtrx,[Lst])

Example:

quartiles([1,2,3,5,10,4]) gives

[[1.0],[2.0],[3.0],[5.0],[10.0]]

quorem Returns the quotient and remainder of the Euclidean division

(by decreasing power) of two polynomials. The polynomials

can be expressed as vectors of their coefficients or in symbolic

form.

quorem((Vect or Poly),(Vect or Poly),[Var])

Example:

quorem([1,2,3,4],[-1,2]) gives [poly1[-1,-4,-

11],poly1[26]]

QUOTE Returns an expression unevaluated.

quote(Expr)

radical_axis Returns the line which is the locus of points at which tangents

drawn to two circles have the same length.

radical_axis(Crcle,Crcle)

randexp Returns a random real according to the exponential

distribution of parameter a>0.

randexp(Real(a))

Example:

randexp(1) gives 1.17118631006

randperm Returns a random permutation of [0,1,2,...,n–1].

randperm(Intg(n))

Example:

randperm(4) gives [2,1,3,0]

ratnormal Rewrites an expression as an irreducible rational fraction.

ratnormal(Expr)

Example:

ratnormal((x^2-1)/(x^3-1)) gives (x+1)/

(x^2+x+1)
