MATLAB Assignment 4 Numerical Methods with First Order Equations Exercise 4.1 1 function [x,y] = Euler(h, x0, y0, interval_length, func) Defines the function of x and y with 5 variables. ‘h’ is the step size for which we want to find x and y values. ‘x0’ is the initial value of x and ‘y0’ is the initial value of y. ‘interval_length’ is the length of the interval starting at x0. ‘func’ is the differential equation that will be evaluated. 2 npoints = floor( interval_length /h) + 1; Determines the number of points that will be evaluated by dividing the length of the intervals by the step size. The 1 is added to avoid missing the last point of the interval. 3 x = zeros(npoints,1); Makes a column of the x values with length of npoints and a width of 1 4 y = zeros(npoints,1); Makes a column of the y values with length of npoints and a width of 1 5 x(1) = x0; Defines the initial value of x for the differential equation 6 y(1) = y0; Defines the initial value of y for the differential equation
