Calling Sequence
|
|
UnitVector[o](i, d, options)
|

Parameters
|
|
|
[o]
|
-
|
(optional) use either [row] or [column] to specify the orientation of the resulting Vector
|
|
i
|
-
|
positive integer; index of the nonzero entry
|
|
d
|
-
|
positive integer; dimension of the resulting Vector
|
|
options

Description
|
|
|
•
|
The UnitVector(i, d) command returns a d-dimensional Vector in which the ith entry is one and all other entries are zero.
|
|
•
|
The UnitVector[row](i, d) command behaves like UnitVector(i, d) except that a row Vector is returned. If the orientation option is omitted or if UnitVector[column](i, d) is used, a column Vector is returned.
