puppeteer

A MATLAB class that can control anything.

The Problem:

• You have a simulation or a function with some parameters. It's complicated
• You want to get a feel for it by twiddling the parameters and seeing how it changes
• It's a pain to write bespoke wrappers for your code and worry about UI generation

The solution

puppeteer does all the hard work of generating UI elements for you.

Generate a new puppeteer instance and tell it the parameters you want to manipulate:

% these are the parameters you want to change
A = 1;
B = 2;

% with corresponding lower 
% bound and upper bounds
lb = [0 0];
ub = [2 5];

p = puppeteer({'A','B'},[A; B],lb,ub,[]);

puppeteer then generates a figure with sliders that allows you to control these parameters. The nice thing now is that any changes you make in the sliders are reflected in the puppeteer object:

p.parameters % stores the updated value, always

Now, there are two ways to hook up puppeteer to your simulation so that changes in puppeteer affect your simulation.

The first is simple: your simulation simply polls p.parameters, and changes its parameters based on that.

The second allows you to configure a callback function so that puppeteer will call this every time you change a parameter.

p.callback_function = my_function_handle;
% puppeteer will call this function with the parameters argument
