Hello,
I have 15 values for x label but they are not consecutive values. for exampl they are bitrate values from 100 kb to 900 kb and 1 mb to 6 mb. but I do not know how can I put them in x axis. I have to put
x=1:15
to have 15 values in x axis. another problem is in x axis we only have numbers such as 0, 5,10 and 15 but I want to have all values in x axis. could you please help me with this issue:? my realese is R2016a. thanks.

You can make the tick labels whatever you want. They don't have to be a literal label of the tick locations.
x = 1:10;
y = sin(x);
xtlbls = {'cat' 'dog' 'tree' 'fruit' '10.413' '⅄∃H' 'red' 'blue' 'words' 'numbers'};
plot(x,y);
xticks(x) % define tick locations explicitly
xticklabels(xtlbls) % define tick labels

Oof. I knew it was R2016b, but I misread the version OP was using.
You can always use set() to set the 'xtick' and 'xticklabel' property of the current axes.

Try this —
figure
plot((1:15), sin((1:15)/2.5))
xtl = [(1:9)*1E8 (1:6)*1E9];
set(gca, 'XTick',(1:15), 'XTickLabel',xtl)

Added x-tick labels to match units in the original post.

Another option for the labels:
xtl = [sprintfc('%3d kb',(1:9)*100) sprintfc('%d mb',1:6)]
figure
plot((1:15), sin((1:15)/2.5))
xtl = [sprintfc('%3d kb',(1:9)*100) sprintfc('%d mb',1:6)];
set(gca, 'XTick',(1:15), 'XTickLabel',xtl)
.

It is not really clear, what you are asking for. But you can set the XTicks and the corresponding lables freely.
x = 1:15;
y = rand(1, 15);
axes('XTick', 1:15, 'XLim', [1, 15], 'XTickLabel', ...
{'A', 'b', '17', '5', 'D', 'now', 'then', '9', '-pi', '10', ...
'11', '12', '-', '14', 'ready'}, ...
'NextPlot', 'add');
plot(x, y);

xticks(1:15)
Lab = [(1:9) + "kb", (1:6) + "mb"]
xticklabels(Lab)
Are you sure that you want linear 1:15 x, but 1:9 vs 10:15 is at different scales? The entry for x=11 is not 2 units more than the entry for x=9, and that is going to lead to misleading plots.

xticks as a function was introduced in the release immediately after the one you have. In your release
set(gca, 'Xtick', 1:15)
set(gca, 'XTickLabel', Lab)
