182 Functions and commands

Dirac Returns the value of the Dirac delta function for a real number.

Dirac(Real)

Example:

Dirac(1) gives 0

e Enters the mathematical constant e (Euler’s number).

egcd Given two polynomials, A and B, returns three polynomials U,

V and D such that:

U(x)*A(x)+V(x)*B(x)=D(x),

where D(x)=GCD(A(x),B(x)), the greatest common

divisor of polynomials A and B.

The polynomials can be provided in symbolic form or as lists

of coefficients in descending order.

Without a third argument, it is assumed that the polynomials

are expressions of x. With a variable as third argument, the

polynomials are expressions of it.

egcd((PolyA, PolyB, [Var]) or egcd(ListA,

ListB, [Var])

Example:

egcd((x-1)^2,x^3-1) gives [-x-2,1,3*x-3]

eigenvals Returns the sequence of eigenvalues of a matrix.

eigenvals(Matrix)

Example:

eigenvals returns [3 -3 -3]

eigenvects Returns the eigenvectors of a diagonalizable matrix.

eigenvects(Matrix)

Example:

eigenvects returns
