propfrac Returns a fraction or rational fraction A/B simplified to Q+r/ B, where R<B or the degree of R is less than the degree of B.

propfrac(Fraction) or propfrac(RatFrac)

Example:

propfrac(28/12) gives 2+1/3

ptayl Given a polynomial P and a value a, returns the Taylor polynomial Q such that P(x)=Q(x – a).

ptayl(Poly, Value, [Var])

Example:

ptayl(x^2+2*x+1,1) gives x^2+4*x+4

q2a Given a quadratic form and a vector of variables, returns the

matrix of the quadratic form with respect to the given variables.

q2a(Expr, Vector)

Example:

q2a(x^2+2*x*y+2*y^2,[x,y]) returns	1 1
	1 2

quantile Given a list or vector, and a quantile value between 0 and 1, returns the corresponding quantile of the elements of the list or vector.

quantile(List, Value) or quantile(Vector, Value)

Example:

quantile([0,1,3,4,2,5,6],0.25) returns 1

quartile1 Given a list or vector, returns the first quartile of the elements of the list or vector. Given a matrix, returns the first quartile of the columns of the matrix.

quartile1(List) or quartile1(Vector) or quartile1(Matrix)

Example:

quartile1([1,2,3,5,10,4]) gives 2
