halftan_hyp2exp(ExprTrig)
Used in programming to go into step-by-step debugging
mode.
Returns the Hamming distance between two integers.
hamdist(Intg,Intg)
Returns the harmonic conjugate of three points or of three
parallel or concurrent lines, or returns the line of conjugates
of a point with respect to two lines.
harmonic_conjugate(Line or Pnt,Line or
Pnt,Line or Pnt)
With three points and a variable as arguments, returns four
points that are in a harmonic division. With three lines and a
variable as arguments, returns four lines that are in a
harmonic division.
harmonic_division(Pnt or Line,Pnt or Line,Pnt
or Line,Var)
Returns 1 if a variable is in an expression, and returns 0
otherwise.
has(Expr,Var)
Returns the first element of a given vector, sequence or string.
head(Vect or Seq or Str)
Returns the value of the Heaviside function for a given real
(i.e. 1 if x>=0, and 0 if x<0).
Heaviside(Real)
Draws a hexagon of side AB in the plane ABP. The other four
corners of the hexagon are named according to the given in
the third, fourth, fifth and sixth arguments.
hexagon(Pnt or Cplx(A),Pnt or
Cplx(B),[Pnt(P)],[Var(C)],[Var(D)],[Var(E)],[
Var(F)])
Returns a point A1 such that vect(C,A1)=k*vect(C,A).
homothety(Pnt(C),Real(k),Pnt(A))
Returns an expression with hyperbolic terms rewritten as
exponentials.
