390 Functions and commands

gramschmidt For a basis B of a vector subspace, and a function Sp that

defines a scalar product on this vector subspace, returns an

orthonormal basis for Sp.

gramschmidt(Basis(B),ScalarProd(Sp))

Example:

gramschmidt([1,1+x],(p,q)->integrate(p*q,x,-

1,1))

gives [1/(sqrt(2)),(1+x-1)/(sqrt(6))/3]

green Used with display to specify the color of the geometrical

object to be displayed.

half_cone Draws a half-cone with vertex A, direction v, half angle t and,

if applicable, height h.

half_cone(Pnt(A),Vect(v),Real(t),[Real(h)])

half_line Draws the half-line AB with A as the origin.

half_line((Pnt or Cplx(A)),(Pnt or Cplx(B)))

halftan2hypexp Returns an expression with sin(x), cos(x), tan(x) rewritten in

terms of tan(x/2) and sinh(x), cosh(x), tanh(x) rewritten in

terms of exp(x).

halftan_hyp2exp(ExprTrig)

Example:

halftan_hyp2exp(sin(x)+sinh(x)) gives 2*tan(x/

2)/(tan(x/2)^2+1)+(exp(x)-1/exp(x))/2

halt Used in programming to go into step-by-step debugging

mode.

hamdist Returns the Hamming distance between two integers.

hamdist(Intg,Intg)

Example:

hamdist(0x12,0x38) gives 3

harmonic_

conjugate

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)
