(angle x y)
Defined at lib/math/vector.lisp:175:2
Compute the angle between vectors X and Y.
Example
> (math/floor (math/deg (angle (vector 1 0) (vector 1 1))))
out = 45
(cross x y)
Defined at lib/math/vector.lisp:140:2
Compute the vector cross product of X and Y.
Example
> (cross (vector 1 0 0) (vector 0 1 0))
out = [0 0 1]
(dot x y)
Defined at lib/math/vector.lisp:119:2
Compute the dot product of vectors X and Y.
Example
> (dot (vector 1 2 3) (vector 3 1 2))
out = 11
(list->vector items)
Defined at lib/math/vector.lisp:31:2
Create a new vector from a list of values.
Example
> (list->vector '(1 2 3))
out = [1 2 3]
(norm x)
Defined at lib/math/vector.lisp:164:2
Compute the norm of vector X (i.e. it’s length).
Example
> (norm (vector 3/2 4/2))
out = 5/2
(null size)
Defined at lib/math/vector.lisp:200:2
Create a vector with a magnitude of 0.
Example
> (null 3)
out = [0 0 0]
(unit x)
Defined at lib/math/vector.lisp:185:2
Convert the vector X into the unit vector. Namely, its direction is
the same but the magnitude is 1.
Example
> (unit (vector 3/2 4/2))
out = [3/5 4/5]
(vector &items)
Defined at lib/math/vector.lisp:17:2
Create a new vector from several values.
Example
> (vector 1 2 3)
out = [1 2 3]
(vector-dim vector)
Defined at lib/math/vector.lisp:7:2
The dimension of this vector.
(vector-item x i)
Defined at lib/math/vector.lisp:53:2
Get the I th element in vector X.
Example
> (define a (vector 5 4 3 2 1))
> (vector-item a 2)
out = 4
> (vector-item a 5)
out = 1
