Given:
x=[3 1 2]
y=[1 1 1]
Is there a way to generate some code to do something like this in MatLab?
x1=y.*x(1)
x2=y.*x(2)
x3=y.*x(3)
where we generate a new variable with a numerical value that correspond to the indices of the array used in the operation?
So the answer should be:
x1=3 3 3
x2=1 1 1
x3=2 2 2
I hope it is clear enough!
Thank you!

Seba.V interesting you show the expected result as one and you acknowledge the result which is completely the other way around.

You can do that more easily with simple matrix-vector multiplication:
z = y(:)*x
producing:
z =
1 1 1
2 2 2
3 3 3
and if you absolutely must create separate vectors for them from ‘z’ (although this is not considered to be efficient programming practice), that is straightforward:
x1 = z(1,:)
x2 = z(2,:)
x3 = z(3,:)
x1 =
1 1 1
x2 =
2 2 2
x3 =
3 3 3
