Simplifies a unit in a unit object.
usimplify(Unit)
Returns the valuation (degree of the term of lowest degree) of
a polynomial. With only a polynomial as argument, the
valuation returned is for x. With a variable as second
argument, the valuation is performed for it.
valuation(Poly,[Var])
Returns the variance of a list
pound
or the list of variances of the columns of a matrix.
variance(Lst||Mtrx,[Lst])
With one point as argument, defines a vector from the origin
to the point. With two points as arguments, defines a vector
from the first point to the second point. With a point and a
vector as arguments, defines a vector beginning from the
point and with direction and magnitude of the vector.
vector(Pnt,Pnt||Pnt,Vect).
Returns the list of the vertices of a polygon or polyhedron.
vertices(Polygon or Polyedr)
Returns the closed list [A,B,...A] of the vertices of a polygon or
polyhedron.
vertices_abca(Polygon or Polyedr)
Returns U such as curl(U)=V.
vpotential(Vect(V),LstVar)
Used to introduce a conditional statement.
Used to indicate the conditions under which a statement
should be executed.
Exclusive or. Returns 1 if the first expression is true and the
second expression is false or if the first expression is false and
the second expression is true. Returns 0 otherwise.
xor(Expr1,Expr2)
Used with display to specify the color of the geometrical
object to be displayed.
Applies a bivariate function to the elements of two lists.
Without the default value its length is the minimum of the
lengths of the two lists and the shorter list is padded with the
default value.
