202 Functions and commands
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
quartile3 Given a list or vector, returns the third quartile of the elements
of the list or vector. Given a matrix, returns the third quartile
of the columns of the matrix.
quartile3(List) or quartile3(Vector) or
quartile3(Matrix)
Example:
quartile3([1,2,3,5,10,4]) returns 5
quartiles Returns a matrix containing the minimum, first quartile,
median, third quartile, and maximum of the elements of a list
or vector. With a matrix as argument, returns the 5-number
summary of the columns of the matrix.
quartiles(List) or quartiles(Vector) or
quartiles(Matrix)
Example:
quartiles([1,2,3,5,10,4])
returns
quorem Returns the Euclidean quotient and remainder of the quotient
of two polynomials, each expressed either in symbolic form
directly or as a vector of coefficients. If the polynomials are
expressed as vectors of their coefficients, this command
returns a similar vector of the quotient and a vector of the
remainder.
quorem(Poly1, Poly2) or quorem(Vector1,
Vector2)
Examples:
quorem(x^3+2*x^2+3*x+4,-x+2) returns [-x^2-4*x-
11, 26]
quorem([1,2,3,4],[-1,2]) returns [[-1, -4, -11]
[26]]
