190 Functions and commands

iquorem Returns the Euclidean quotient and remainder of two integers.

iquorem(Integer1, Integer2)

Example:

iquorem(63, 23) returns [2, 17]

jacobi_symbol Returns the Jacobi symbol of the given integers.

jacobi_symbol(Integer1, Integer2)

Example:

jacobi_symbol(132,5) gives -1

laplacian Returns the Laplacian of an expression with respect to a vector

of variables.

laplacian(Expr, Vector)

Example:

laplacian(exp(z)*cos(x*y),[x,y,z]) returns

–x^2*cos(x*y)*exp(z)-

y^2*cos(x*y)*exp(z)+cos(x*y)*exp(z)

lcoeff Returns the coefficient of the term of highest degree of a

polynomial. The polynomial can be expressed in symbolic

form or as a list.

lcoeff(Poly) or lcoeff(List) or lcoeff(Vector)

Example:

lcoeff(-2*x^3+x^2+7*x) returns -2

legendre_symbol With a single integer n, returns the Legendre polynomial of

degree n. With two integers, returns the Legendre symbol of

the second integer, using the Legendre polynomial whose

degree is the first integer.

legendre_symbol(Integer1, [Integer2])

Example:

legendre(4) gives 35*x^4/8+-15*x^2/4+3/8 while

legendre(4,2) returns 443/8 after simplification

length Returns the length of a list, string or set of objects.

length(List) or length(String) or

length(Object1, Object2,…)

Example:

length([1,2,3]) gives 3
