finding the transformation vector?

Let say I have a vector A:

A=[1 2 2 3 3 3 4 4 4 4];

then I transform A to B by x so that [ Ax = B ]:

B=[4 1 4 4 1 1 2 4 6 5];

How do I find x ?

Thanks!

You mean A.*x = b or A*x = b ?

[Vilém Frynta]

A = [1 2 2 3 3 3 4 4 4 4];
B = [4 1 4 4 1 1 2 4 6 5];

x = B./A

x = 1×10
