Hi ,please help , I need to plot signals u(t-3),u (t+1), z(-t-3),,z(2t+2),u(-2n-1) and u(3n+2) using subplot and add title ,grid and axis labels
t=[-4:0.2:4]; n=[-2:0.1:2]; subplot(3,2,1) plot(t,heaviside(t-3)) grid on; title('Time shifted signal') xlab...

Is this code ok?It asked to plot function together with hold on...syms x y; t=-2:0.1:2 n=-2:0.1:2 x=2*sin(4*pi*t); y=2*sin(4*pi*n); plot(t,x,'r',n,y,'g'); hold on; title('function'); legend('x function', 'y function'); grid on;
Is this code ok?It asked to plot function together with hold on. But when I run code,I have just y function ? syms x y; ...
