Hello There!
I have N number of vectors recorded into workspace. I need to perform combination among themselves by using allcomb. How could I introduce the vectors into the command (allcomb) in the form of B = ALLCOMB(A1,A2,A3,...,AN).
Thanks inadvance....

My variables are dynamic. the number of variables is continuously changing. I can not write them as you said. I have to define a set of variable like B = ALLCOMB(A1,A2,A3,...,AN). I do not know how to do this.

READ THE RESPONSE BY BRUNO. Learn how to use cell arrays instead of dynamically naming your variables. Numbered variables is a terrible programming style, that if you continue to follow it, will continuously lead you into problems, just as you are having now.

Create a CELL array, and get rid of the method of naming your variables with number 1,2,....
C = {A1, A2, A3, ..., AN}
B = allcomb(C{:});
