Functions and commands 185

Examples:

factorial(4) returns 24

factorial(1.2) returns 1.10180249088

fMax Given an expression in x, returns the value of x for which the

expression has its maximum value. Given an expression and

a variable, returns the value of that variable for which the

expression has its maximum value.

fMax(Expr,[Var])

Example:

fMax(-x^2+2*x+1,x) gives 1

fMin Given an expression in x, returns the value of x for which the

expression has its minimum value. Given an expression and a

variable, returns the value of that variable for which the

expression has its minimum value.

fMin(Expr,[Var])

Example:

fMin(x^2-2*x+1,x) gives 1

format Returns a real number as a string with the indicated format

(f=float, s=scientific, e=engineering).

format(Real, String)

Example:

format(9.3456,"s3") returns 9.35

fracmod For a given integer n (representing a fraction) and an integer

p (the modulus), returns the fraction a/b such that n=a/b(mod

p).

fracmod(Integern, Integerp)

Example:

fracmod(41,121) gives 2/3

froot Returns a vector containing the roots and poles of a rational

polynomial. Each root or pole is followed by its multiplicity.

froot(RatPoly)

Example:

froot returns [0 3 1 2 3 -1]
