Example:
Dirac(1) gives 0
e
Enters the mathematical constant e (Eulers 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 coeicients 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
eigVl
Returns the Jordan matrix associated with a matrix when the eigenvalues are calculable.
EVAL
Evaluates an expression.
eval(Expr)
