I have some question in MATLAB homework

I have some question in my MATLAB homework Please help me to solve them.

[Guillaume]

"Please help me to solve them"

From the lack of any question on your part, sounds more like Please do my homework for me.

Which of course we won't do.

So, not only did Mutlu not do his own howework, but once someone had done his homework for him he then closes the question and deletes the question body so that it is then useless for everybody else.

Answers is there to benefit everybody. It is not a help me cheat on my homework service.

Answer 1

[Yuvaraj Venkataswamy]

Please check this.

%%%%%%9.

t=-10:1:10;

x1=exp(-(t));

figure;

plot(t,x1,'r-');

hold on

x2=exp(-(t-2));

plot(t,x2,'g-');

hold on

x3=exp(-(t+2));

plot(t,x3,'b-');

xlim([-10 10])

%%%%%%%10.

t=-10:1:10;

x1=exp(-(t));

figure;

plot(t,x1,'r-');

hold on

x2=exp(-(2*t));

plot(t,x2,'g-');

hold on

x3=exp(-(0.5*t));

plot(t,x3,'b-');

xlim([-10 10]);

%%%%%%%%11.

t=-10:1:10;

x1=t.^3;

figure;

plot(t,x1,'r-');

hold on

x2=(-t).^-3;

plot(t,x2,'g-');

xlim([-10 10])

t=-10:1:10;

x1=exp(-0.2*t).*sin(t);

figure;

plot(t,x1,'r-');

hold on

x2=exp(-0.2*(-t)).*sin(-t);

plot(t,x2,'g-');

xlim([-10 10])

[Walter Roberson]

I would suggest using linspace(-10,10) instead of -10:1:10 as the : version is only 21 points.

[Yuvaraj Venkataswamy]

Yes. In this, I have considered step increment is 1. So, I got 21 points.
