I want to make create a traveling sine wave with with a specific frequency and wavelength moving with a specific speed v. How can I make the code? I can make a sine wave easily but don't know how to write code for traveling wave! Thank you.

What do you mean by traveling? Like you want the sine wave to be animated like it's slowly traveling to the right or something? If so, just change the phase and replot it. Put a pause() in to change the speed.

For R2014b onwards, use animatedline with a limited number of points to be retained. drawnow() or pause() after you update the points.
