====STEPS - scale generator====

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

<code>STEPS <var>X</var> <var>DX</var> <var>N</var> <var>TYPE</var></code>

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

{|
|-
|X
|1st x<nowiki>-</nowiki>value
|no default
|-
|DX
|X increment or factor
|default = 0
|-
|N
|number of values
|default = 1
|-
|TYPE
|scale type
|
|}

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

{|
|-
|<var>Y</var>
|scale vector
|}

=====Function:=====

This atom generates a series of N values, and stores it in the output vector <var>Y</var>. The main use of this function is the generation of the X-scale vectors of graph-items.

{|
|-
|<var>TYPE</var>=0 or <var>TYPE</var>=ARITHMETICAL
|<nowiki>-</nowiki>>
|Y[i] = <var>X</var> + i.<var>DX</var>
|-
|TYPE=1 or <var>TYPE</var>=GEOMETRICAL
|<nowiki>-</nowiki>>
|Y[i] = <var>X</var> . <var>DX</var>i
|-
|with: i = 0, 1, .., N-1
