I am plotting a pattern as illustrated in link shown below. I want to create an image of fixed size.
The whole image should be filled by repeating unit blocks which consist of black and green regions. The width of a unit block and its black region change from
100 (or even larger values), and from
The ratio between a black region and a unit block is given as
1.055^(-lambda0). More preferably, the width of a unit block changes randomly from
Lambda0(1 - errorfactor) to
lambda0(1 + errofactor), so that the average value of the unit blocks are still
lambda0 but each individual block may vary slightly.
