this matlab code does not want to run.is there anything wrong with the codes?the codes are for the question attached with this post

the codes are supposed to give me a plot for the specified range of the independent variable

July quota Problem 8 x = (pi/4 pi/2]; *Time period initial = 4/3; Initial condition The RHS of ODES f = @(x,y) (1-3*y). *sec (x)./cos (x); [t,y] = ode45 (f,x, initial); Computing the solution using ODE 45 function figure plot(t,y), xlabel('x'), ylabel('Y'); 4Plotting the solution title('Problem 8'); - y'cosx+ (3) 1) secx = 0, y = for range of x [TT/4, 1/2]
