MATLAB: All combinations not being generated

Question

Hello everyone,

Running a code to get all combinations of vector. Each combination is unique on its own. Meaning, [.4, .1, .1] is different from [.1, .1, .4] and so on.

Ok, here is the code

A = [0.4, 0.25, 0.1] %vector
[A1,A2,A3] = ndgrid(A);
my_matrix= [A3(:),A2(:),A3(:)] 

It does not give all combinations. In fact, the example stated above is missing.

If you run it and have a look at the last column, you'll see it is copy of the first column.

What am I doing wrong?

Thanks in advance!

Answer 1

update: In line 3 of the code A3(:) is repeated twice, resulting in the 'error'

Follwing is what it should read :

my_matrix= [A1(:),A2(:),A3(:)]
