Examples of vector and point calculations
MeaningExpression
Determines vector translation from point a to point b.vec(a,b)
Determines unit vector direction from point a to point b.vec1(a,b)
Determines vector of length L in the direction from point a to
point b.
L*vec1(a,b)
Determines point b, which is a translation of the point a
through vector v.
a+v
Determines point b located 5 units away from point a at an
angle of 20 degrees. Note that [5<20] is a vector in polar co-
ordinates.
a+[5<20]

Calculate the Length of a Vector
The abs function calculates the length of a vector.
abs(v) Calculates the length of vector v, a nonnegative real number.
In spherical coordinates (dist<ang<ang), the dist is the length of the vector.
The following example calculates the length of the vector [1,2,3]:
abs([1,2,3])
