SubVector()

Extracts a number of elements from a vector.

Added to Version 2014.

sub_vector = SubVector(vector v, integer start, integer length)

Argument	Contents
v	The input vector
start	The position of the first element extracted
length	The number of elements extracted

A vector containing the specified elements of v, or null, if start and length do not specify any elements.

If start is null, SubVector() extracts from the beginning of v.
If length is null, SubVector() returns all the elements of the vector beginning with start.
SubVector() does not modify v; it creates a new vector containing a subset of the elements.

a = {1,1,3,4,5}

v = a2v(a)

v2 = SubVector(v, 2, 3) // v2 = [1,3,4]

Error Type	Meaning
Error	Start is less than one, or length is less than zero
