Given below is the implementation of second problem in matlab which is the only programming assignment.
y_0 = 1;
y_n = y_0;
for interval = [0.1,0.01,0.001]
y_n=y_0;
for t = 0.0: interval: 1.0
y_n=y_n+(((2*y_n)-exp(-1.0*t)-1)*interval);
end
sprintf('approximate value of y(t) at t=1.0 taking time gap = %f is
%f ',interval,y_n)
end

There are 5 errors in the MATLAB function code below. This function is supposed to numerically approximate a system of ODEs using Euler's method with a for loop. (a) What are the errors? (b) How would you fix them? 88 388 function (t, y) euler_system (ODEFUN, TSPAN, YO, H) %EULER_SYSTEM (ODEFUN, TSPAN, YO, H) will numerically solve a system fof first order ODEs using Euler's Method, where ODEFUN is a %column vector of the derivative functions, TSPAN is a vector...
Please help me do both problems if you can, this is due tonight and this is my last question for this subscription period. (Thank you) Euler's method for a first order IVP y = f(x,y), y(x) = yo is the the following algorithm. From (20, yo) we define a sequence of approximations to the solution of the differential equation so that at the nth stage, we have In = {n-1 +h, Yn = Yn-1 +h. f(xn-1, Yn-1). In this exercise...

According to the Existence and Uniqueness theorem, the differential equation (t−5)y′+ysin(t)=5t necessarily has a unique solution on the interval 0<t≤5. TRUE FALSE A numerical method is said to converge if its approximate solution values for a differential equation y′=f(t,y), y1,y2,...,yn, approach the true solution values ϕ(t1),ϕ(t2),...,ϕ(tn), as the stepsize h→∞. TRUE FALSE If a numerical method has a global truncation error that is proportional to the nth power of the stepsize, then it is called an nth order method. TRUE...
