Simple rigid body 2D physics of a circle in MATLAB
% Define parameters
radius = 1; % circle radius
mass = 1; % circle mass
speed = 10;
angle = deg2rad(45);
[xv,yv]=pol2cart(angle,speed);
initialPosition = [-7, -7]; % initial position (x, y)
initialVelocity = [xv, yv]; % initial velocity (vx, vy)
timeStep = 0.1; % time step
simulationTime = 10; % total simulation time

Create stimulus frame movie from a previous opticka experiment.
% This script loads a previous opticka experiment, then uses the screen and
% stimulus and task values to generate a series of movies or pictures for
% each stimulus frame. This assumes a single variable (i.e. angle). It runs
% 0.25 only showing fixation cross, then 1.5 secs of the stimulus, then
% another 0.25 seconds blank.
%%
% lets load from the saved MAT file
[mat,p] = uigetfile('*.mat','Select the Experiment MAT file');
if isnumeric(mat); return; end
