Use matlab In Problems 5-10 use a numerical solver and Euler's method to obtain a four-decimal approximation of the indicated value. First use h 5 0.1 and then use h 5 0.05. 8. y'=xy+ sqrt(y), y(0)=1, y(0.5) I tried this method, but it gives me errors "un recongnized function or variable at 'xy'. Error in live 5 and error in line 17 close all clear clc f=@(x,y) xy+sqrty; % Given ODE x0=0; xf=0.5; % Interals of x y0=1; % Intital condition h1=0.1; % Step Size 1 yl=euler(x0, yo, xf, h1, f); fprintf('For h=0.1, y(0.5) - %.4f/n', y1(end)) y2=euler (x0, yo, xf, h2, f); fprintf('For h=0.05, y(0.5) - %.4f/n', y2(end)) function y=euler(x0, yo, xf, h, f) y(1)=y0; x=x0:h:xf; for i=1:length(x)-1 f1-f(x(i), y(i)); y(i+1)=y(i)+h*f1; %Euler's Update end end
