I have two arrays of the same size, I want to find a scalar which when you multiple the one array by the scalar (number) get's it as close to the other as pssible.
e.g. Two arrays A and B, scalar c.
A=cB
What would be the best way to code this, I was thinking either a fitting or just a for loop but I am unsure how to code it. I need to get the final value for c.
Thanksyou!

c = A(:) \ B(:)
For example:
>> A = rand(2,3);
>> B = A*0.23;
>> c = A(:) \ B(:)
c = 0.23000
