I need some suggestions for drawing flowchart for my process. The whole process is divided into three modules
- Module 1 Random: The inputs to this module are two scalars $m$ and $n$. It outputs to matrices $\mathbf{A}$ and $\mathbf{B}$.
- Module 2 Deterministic: The input here is a range of angle $\theta$. It outputs two vectors $\mathbf{x}$ and $\mathbf{y}$ computed from a fixed relationship involving $\theta$
- Module 3: It combines $\mathbf{A},\mathbf{B},\mathbf{x},\mathbf{y}$ according to a known relationship.
My question is
- I want have three separate boxes for these the modules. Module 1 and 2 are drawn in parallel in top half of chart. Module 3 that goes in bottom half extends from southwest corner to module 1 to southeast corner of module 2.
- Since within each module module I need to show its internal process, I want to have a flexible code so that change in one does not effect other blocks.
- In Module 2, I want to draw a circle showing $\theta$ (like below)
Which tool should I be using to draw this flowchart?
