- Tracks the motion of 300 molecules within a 2-D space, over a series of time steps - On each time step every molecule will move by a random amount in the x and y directions - Your model needs to calculate the steps in space for all 300 molecules, store them in an array and repeat this for 100 time steps - Start the model with all molecules at the [0,0] point - At each time point plot the position of the molecules in a scatter plot and run this for all time points so that a 'movie' of the molecular motion is created Amend your MATLAB model of a single set of diffusing molecules (no membrane) : - Create a histogram of the x-position values at each time point - Plot out the histogram for each time point, again as a movie so that you can visualise the sequence - Create a 2-D histogram so that you can visualise the spread in molecular concentration in x and y directions - You should also plot out the mean and standard deviation of the x and y position of your particles through time
