Description

The natural Stream Evaluator returns a vector of natural numbers. This is useful for creating a sequence of numbers 0...N for plotting an x-axis.

Sample syntax:

let(a=natural(10))

The repeat Stream Evaluator creates a vector with a number repeated N times. This useful for plotting a straight line.

Sample syntax:

let(a=repeat(5.5, 100))
