iter Function (GPL)

Syntax

iter(<from>, <to>, <step>)

<from>. The first value in the new column. Subsequent values are iterated from this one.

<to>. The maximum value that the new column can contain.

<step>. A value defining the amount by which values are iterated.

Description

Creates a new column of data with values in a specified range. Intermediate values are calculated by adding the step value to the previous value. For example, iter(1,5,1) generates the values 1, 2, 3, 4, 5. iter(1,10,2) generates the values 1, 3, 5, 7, 9. Note that 10 is not included in the second example because it cannot be iterated from the previous value.

Examples

Figure 1. Example: Creating a graph from an equation

DATA: x = iter(-100,100,1)
TRANS: y = eval(x**2)
ELEMENT: line(position(x*y))
