====VSPLIT - split vectors====

=====Usage:=====

<code>VSPLIT <var>x</var> <var>l</var> <var>o</var> <var>inc</var> <var>ref</var></code>

=====Inputs:=====

{|
|-
|x
|The vector to be split. There is no default.
|-
|l
|The number of output elements. This must be a number greater than <code>0</code>. There is no default.
|-
|o
|The index of the first element (i.e. the offset). This must be a number greater than or equal to <code>0</code>. The default is <code>0</code>.
|-
|inc
|The increment. This must be a number greater than <code>0</code>. The default is <code>1</code>.
|-
|ref
|A flag specifying whether the vector should be copied in reverse. This can be one of the following keywords:<code>0</code>|<code>N</code>|<code>No</code> or <code>1</code>|<code>Y</code>|YesThe default is <code>No</code>.
|}

=====Outputs:=====

{|
|-
|y
|The split part of vector (extracted elements) with the length l.
|}

=====Description:=====

This atom can be used to split a vector or (in other words) to extract a sub-vector from a vector.

{|
|-
|
|
|-
|ref=0 or NO:
|y[i] = <var>x</var>[<var>o</var> + i.<var>inc</var>]
|-
|ref=1 or YES:
|y[i] = <var>x</var>[n-<var>o</var>-(i+1).<var>inc</var>]
|-
|with: i=0, 1, .., l-1
|}

For both modes the parameters <var>l</var>, <var>o</var> and <var>inc</var> must match following conditions:

<var>o</var> >= 0; <var>inc</var> and <var>l</var> > 0; <var>o</var> + (<var>l</var>-1).<var>inc</var> < number of elements of <var>x</var>.
