Description
Represents an element of R^N. Usual operations are implemented.
NOTE: for 2D and 3D vectors, there are available the classes RealVector2D and RealVector3D which are roughly 10% faster than RealVector.
Class Methods
.rand
random vector.
Arguments:
| size |
dimension of vector. |
| lo, hi |
range of values |
.canonB
ith element of canonic base of R^N.
Instance Methods
.cross
cross product
NOTE: The vectors should be 3 dimensional, and no error checking is done for speed.
.asPoint
.theta
.zero
Make a zero vector
Arguments:
| dim |
Dimensions of the vector. This is not needed for |
