%This function is used by the ODE solver to determine reaction rates %at each time step. This file must be save with the name of the equation. %You can use this equation with the accompanying introtoODEs.m %This is the example for a generic reaction: % Enzyme + Substrate  Complex -> Product function ydot = example(t, y, k) %Function named example (hence example.m) %Create an output array ydot = zeros(4, 1); %Four rows, one per species (four in this case) %Define variables based on input initial conditions array %For example, if the array is y = [1 3 8 10], y(2) will call the value 3 Substrate = y(1); Enzyme = y(2); Complex = y(3); Product = y(4); %Define rate constants k1 = k(1); k2 = k(2); k3 = k(3); %Governing equations ydot(1) = -k1 * Substrate * Enzyme + k2 * Complex; ydot(2) = -k1 * Substrate * Enzyme + k2 * Complex + k3 * Complex; ydot(3) = k1 * Substrate * Enzyme - k2 * Complex - k3 * Complex; ydot(4) = k3 * Complex; end 

PLEASE I NEED HELP!! I do not understand what to do. The name of articles are

A Model for the Tissue Factor Pathway to Thrombin 11. A MATHEMATICAL SIMULATION* (Received for publication, March 10, 1994, and in revised form, June 28, 1994) Kenneth C. Jones and Kenneth G. MannS From the Department of Biochemistry, Health Science Complex, University of Vermont, College of Medicine, Burlington, Vermont 05405-0068

The goal of this assignment is to reproduce the figures in the paper by using MATLAB to implement the model described in the Jones & Mann paper. This assignment combines and builds off of the coding you have been exposed to and the rate equations for enzyme kinetics. By completing this implementation, you will have gained an invaluable skillset of being able to use mathematical models to test hypotheses about the dynamics of biological systems Template MATLAB scripts will be provided separately. Submit the following components for grading (100 pts possible): 1. One matlab script (.m file) that: a. Encodes the differential equations that describe the coagulation cascade (10 pts) 2. One matlab script (.m file) that: Calls the differential equation script to reproduce each figure, complete with axes labels, titles, and legends (6x 10pts) Contains thoughtful documentation (i.e. well commented code) (10 pts) a. b. 3.
