Please I want to do something like this that will remove only the bottom x-axis

Use this to remove even the x-tick label as in the above picture:

plot(1:10) % your plot here
set(gca,'XAxisLocation','top', 'box','off', 'XTick', [])

If you need labels:

set(gca,'XAxisLocation','top', 'box','off')

Look here and here

Thank you very much.

It works

Removing the box also seems like it removes the right y-axis. Is there any way to avoid this?

If you just want to restore the right side of the box (without ticks or tick labels on the right side), you could do this:

plot(1:10)
set(gca,'XAxisLocation','top', 'box','off')
xline(max(xlim)) % <<< this draws the right side of the "box"

In general, to move your x-asix on top:

set(gca,'XAxisLocation','top')

To hide the axis:

set(gca,'xtick',[])

or

h = gca;
h.XAxis.Visible = 'off';

Thanks Vero,

In this case will I be able to turn off only the bottom x-axis off and leave the top x-axis?

Thanks

I gave you more options because your need is not clear to me. You should try one of the above. I think the first one could be fine:

x = 0:pi/100:2*pi;
y = sin(x);
plot(x,y)
set(gca,'XAxisLocation','top')
