I have two matrix with different sizes:
A (13*5)
B (9*5)
I want to plot each cloumn of A next to similar coulmn of B, but with diferent color. (i.e. I should have 10 box within my boxplot plot)

There are likely a few different ways to do this task. Here is one straightforward way:
A = rand(13,5);
B = rand(9,5);
xc = 1:5;
offset = 0.1;
w = 0.1;
figure
hold on
boxplot(A,'Positions',xc-offset,'Widths',w,'Colors','r');
boxplot(B,'Positions',xc+offset,'Widths',w,'Colors','k');
The documentation for boxplot explains most of what I have done here. Check out the documentation for the hold command, too, if you are unfamiliar with that.

what will happen if the number of clumn and rows are not similar in both matrix? lets say:
A=9*16
B=13*17
I would like to have the boxplot of this two matrix on the same figure!

The solution I posted can be very easily changed to the case where the matrices are different sizes, but you didn't seem to like that solution, so I won't post that.
Especially when the data are different sizes, how do you want to decide which columns should be near each other?
You need to add more detail about what you want. You are leaving us to guess too much.
