I want all the sets of randomly mixed values of A and B and then I need to iterate them
So, there are two questions 
1) How do I randomly pick one set of A and B and then pass it on the array?
2) How do I iterate all the sets of values without using for loop?

Sorry, Autocorrect!

How can I iterate all the values without using for loop?

Since there are many combinations I want to avoid for loop. Please let me know

I have 2 variables named A and B

A  has the range from -0.2 to 2.2 
B has the range from  -3.2 to 0.2

I need all the possible to combinations of A and B in 0.1 steps

for example 

A                        B
0.1                  0.2
-0.1               -0.3 and so on 

How do I randomly generate this?

I am not sure what you want, but this might help.

a=-.2:.1:2.2;
b=-3.2:.1:.2;
r1=randi(numel(a))
r2=randi(numel(b))
c=[a(r1) , b(r2)]

In your first question you hat the word "random" so I thought you wanted a random choice , in the range. 
Now I see that you don't wand random.
So what do you want? 
Just a set of all possible combinations? do you know how big that will be?

This looks like homework.
I don't do homework questions.
I did show you how to do part of your question, and now I am out!
