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)]

Thank you
I can i iterate all the values without using for loop,
SInce there are many combinations I want to avoid 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 Thank you

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?
 DAS


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?

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!

No sir, It is not. I can pass it via for loop but I don't want to take that approach.
Kindly let me know

No sir, It is not. I can pass it via for loop but I don't want to take that approach.
Kindly let me know
as before, please post after the quoted reply, not before it. it makes it easier for readers to follow the conversation.
I assume you didn't actually mean 'randomly', but you are looking for all of the combinations.
What you are doing looks like the generation of a 2d coordinate mesh, given vectors A and B. You can use the meshgrid function to make all of those combinations.
>> A = 1:0.2:2;B = 10:0.2:11;[aa, bb] = meshgrid (A,B) aa =
1.0000 1.2000 1.4000 1.6000 1.8000 2.0000 1.0000 1.2000 1.4000 1.6000 1.8000 2.0000 1.0000 1.2000 1.4000 1.6000 1.8000 2.0000 1.0000 1.2000 1.4000 1.6000 1.8000 2.0000 1.0000 1.2000 1.4000 1.6000 1.8000 2.0000 1.0000 1.2000 1.4000 1.6000 1.8000 2.0000
bb =
10.000 10.000 10.000 10.000 10.000 10.000 10.200 10.200 10.200 10.200 10.200 10.200 10.400 10.400 10.400 10.400 10.400 10.400 10.600 10.600 10.600 10.600 10.600 10.600 10.800 10.800 10.800 10.800 10.800 10.800 11.000 11.000 11.000 11.000 11.000 11.000
Now, the positions of aa and bb give you every combination of A, B.
if you want this reshaped as a single array, you could use:
>> C = [aa(:), bb(:)] C =
1.0000 10.0000 1.0000 10.2000 1.0000 10.4000 1.0000 10.6000 1.0000 10.8000 1.0000 11.0000 1.2000 10.0000 1.2000 10.2000 1.2000 10.4000 1.2000 10.6000 1.2000 10.8000 1.2000 11.0000 1.4000 10.0000 1.4000 10.2000 1.4000 10.4000 1.4000 10.6000 1.4000 10.8000 1.4000 11.0000 1.6000 10.0000 1.6000 10.2000 1.6000 10.4000 1.6000 10.6000 1.6000 10.8000 1.6000 11.0000 1.8000 10.0000 1.8000 10.2000 1.8000 10.4000 1.8000 10.6000 1.8000 10.8000 1.8000 11.0000 2.0000 10.0000 2.0000 10.2000 2.0000 10.4000 2.0000 10.6000 2.0000 10.8000 2.0000 11.0000
Or however else you want to manipulate the array to make it useful for you.

Great answer Nicholas! Ganesh: does this do what you want?
Do you still want any randomness ?
